Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541518, here are decompositions:

11 + 31541507 = 31541518
89 + 31541429 = 31541518
101 + 31541417 = 31541518
251 + 31541267 = 31541518
389 + 31541129 = 31541518
401 + 31541117 = 31541518
467 + 31541051 = 31541518
479 + 31541039 = 31541518

Showing the first eight; more decompositions exist.
