Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576696, here are decompositions:

23 + 31576673 = 31576696
113 + 31576583 = 31576696
167 + 31576529 = 31576696
257 + 31576439 = 31576696
269 + 31576427 = 31576696
293 + 31576403 = 31576696
443 + 31576253 = 31576696
509 + 31576187 = 31576696

Showing the first eight; more decompositions exist.
