Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504996, here are decompositions:

53 + 31504943 = 31504996
113 + 31504883 = 31504996
197 + 31504799 = 31504996
293 + 31504703 = 31504996
389 + 31504607 = 31504996
449 + 31504547 = 31504996
503 + 31504493 = 31504996
557 + 31504439 = 31504996

Showing the first eight; more decompositions exist.
