Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572676, here are decompositions:

29 + 31572647 = 31572676
263 + 31572413 = 31572676
353 + 31572323 = 31572676
449 + 31572227 = 31572676
593 + 31572083 = 31572676
617 + 31572059 = 31572676
647 + 31572029 = 31572676
659 + 31572017 = 31572676

Showing the first eight; more decompositions exist.
