Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541368, here are decompositions:

71 + 31541297 = 31541368
101 + 31541267 = 31541368
227 + 31541141 = 31541368
239 + 31541129 = 31541368
251 + 31541117 = 31541368
317 + 31541051 = 31541368
347 + 31541021 = 31541368
389 + 31540979 = 31541368

Showing the first eight; more decompositions exist.
