Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525624, here are decompositions:

17 + 31525607 = 31525624
23 + 31525601 = 31525624
71 + 31525553 = 31525624
227 + 31525397 = 31525624
257 + 31525367 = 31525624
281 + 31525343 = 31525624
293 + 31525331 = 31525624
461 + 31525163 = 31525624

Showing the first eight; more decompositions exist.
