Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451926, here are decompositions:

17 + 31451909 = 31451926
89 + 31451837 = 31451926
173 + 31451753 = 31451926
197 + 31451729 = 31451926
227 + 31451699 = 31451926
269 + 31451657 = 31451926
347 + 31451579 = 31451926
929 + 31450997 = 31451926

Showing the first eight; more decompositions exist.
