Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541098, here are decompositions:

47 + 31541051 = 31541098
59 + 31541039 = 31541098
107 + 31540991 = 31541098
137 + 31540961 = 31541098
227 + 31540871 = 31541098
311 + 31540787 = 31541098
389 + 31540709 = 31541098
419 + 31540679 = 31541098

Showing the first eight; more decompositions exist.
