the answer would be 6 even numbers greater than 2 and less than 20 would be equal to the sum of two prime numbers.
explanation:
even numbers greater than 2 and less than 20 would be 4, 6, 8, 10, 12, 14, 16, and 18.
the prime numbers we can use would be 2, 3, 5, 7, 11, and 13.
13+3=16 and 13+5=18.
11+3=14.
7+3=10 and 7+5=12.
finally, 5+3=8.
that makes a total of 6 even numbers.
