Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542766, here are decompositions:

89 + 31542677 = 31542766
107 + 31542659 = 31542766
179 + 31542587 = 31542766
257 + 31542509 = 31542766
347 + 31542419 = 31542766
389 + 31542377 = 31542766
443 + 31542323 = 31542766
569 + 31542197 = 31542766

Showing the first eight; more decompositions exist.
