Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607792, here are decompositions:

3 + 31607789 = 31607792
103 + 31607689 = 31607792
109 + 31607683 = 31607792
163 + 31607629 = 31607792
193 + 31607599 = 31607792
211 + 31607581 = 31607792
241 + 31607551 = 31607792
331 + 31607461 = 31607792

Showing the first eight; more decompositions exist.
