Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508696, here are decompositions:

13 + 31508683 = 31508696
19 + 31508677 = 31508696
127 + 31508569 = 31508696
139 + 31508557 = 31508696
337 + 31508359 = 31508696
367 + 31508329 = 31508696
409 + 31508287 = 31508696
463 + 31508233 = 31508696

Showing the first eight; more decompositions exist.
