Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541044, here are decompositions:

5 + 31541039 = 31541044
23 + 31541021 = 31541044
53 + 31540991 = 31541044
83 + 31540961 = 31541044
173 + 31540871 = 31541044
257 + 31540787 = 31541044
317 + 31540727 = 31541044
401 + 31540643 = 31541044

Showing the first eight; more decompositions exist.
