Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588352, here are decompositions:

31 + 31588321 = 31588352
151 + 31588201 = 31588352
181 + 31588171 = 31588352
223 + 31588129 = 31588352
349 + 31588003 = 31588352
373 + 31587979 = 31588352
409 + 31587943 = 31588352
571 + 31587781 = 31588352

Showing the first eight; more decompositions exist.
