Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541068, here are decompositions:

17 + 31541051 = 31541068
29 + 31541039 = 31541068
47 + 31541021 = 31541068
89 + 31540979 = 31541068
107 + 31540961 = 31541068
197 + 31540871 = 31541068
281 + 31540787 = 31541068
359 + 31540709 = 31541068

Showing the first eight; more decompositions exist.
