Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542844, here are decompositions:

17 + 31542827 = 31542844
167 + 31542677 = 31542844
257 + 31542587 = 31542844
467 + 31542377 = 31542844
503 + 31542341 = 31542844
521 + 31542323 = 31542844
563 + 31542281 = 31542844
647 + 31542197 = 31542844

Showing the first eight; more decompositions exist.
