Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542604, here are decompositions:

17 + 31542587 = 31542604
167 + 31542437 = 31542604
227 + 31542377 = 31542604
263 + 31542341 = 31542604
281 + 31542323 = 31542604
491 + 31542113 = 31542604
521 + 31542083 = 31542604
593 + 31542011 = 31542604

Showing the first eight; more decompositions exist.
