Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525888, here are decompositions:

47 + 31525841 = 31525888
71 + 31525817 = 31525888
89 + 31525799 = 31525888
101 + 31525787 = 31525888
239 + 31525649 = 31525888
281 + 31525607 = 31525888
389 + 31525499 = 31525888
467 + 31525421 = 31525888

Showing the first eight; more decompositions exist.
