Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525288, here are decompositions:

5 + 31525283 = 31525288
59 + 31525229 = 31525288
167 + 31525121 = 31525288
251 + 31525037 = 31525288
257 + 31525031 = 31525288
281 + 31525007 = 31525288
449 + 31524839 = 31525288
479 + 31524809 = 31525288

Showing the first eight; more decompositions exist.
