Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625524, here are decompositions:

17 + 31625507 = 31625524
71 + 31625453 = 31625524
113 + 31625411 = 31625524
131 + 31625393 = 31625524
173 + 31625351 = 31625524
263 + 31625261 = 31625524
467 + 31625057 = 31625524
617 + 31624907 = 31625524

Showing the first eight; more decompositions exist.
