Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541038, here are decompositions:

17 + 31541021 = 31541038
47 + 31540991 = 31541038
59 + 31540979 = 31541038
167 + 31540871 = 31541038
251 + 31540787 = 31541038
311 + 31540727 = 31541038
359 + 31540679 = 31541038
401 + 31540637 = 31541038

Showing the first eight; more decompositions exist.
