Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511696, here are decompositions:

19 + 31511677 = 31511696
43 + 31511653 = 31511696
127 + 31511569 = 31511696
157 + 31511539 = 31511696
163 + 31511533 = 31511696
193 + 31511503 = 31511696
409 + 31511287 = 31511696
607 + 31511089 = 31511696

Showing the first eight; more decompositions exist.
