Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541134, here are decompositions:

5 + 31541129 = 31541134
17 + 31541117 = 31541134
83 + 31541051 = 31541134
113 + 31541021 = 31541134
173 + 31540961 = 31541134
263 + 31540871 = 31541134
311 + 31540823 = 31541134
347 + 31540787 = 31541134

Showing the first eight; more decompositions exist.
