Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588264, here are decompositions:

11 + 31588253 = 31588264
17 + 31588247 = 31588264
107 + 31588157 = 31588264
353 + 31587911 = 31588264
557 + 31587707 = 31588264
563 + 31587701 = 31588264
641 + 31587623 = 31588264
647 + 31587617 = 31588264

Showing the first eight; more decompositions exist.
