Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471924, here are decompositions:

17 + 31471907 = 31471924
23 + 31471901 = 31471924
41 + 31471883 = 31471924
101 + 31471823 = 31471924
137 + 31471787 = 31471924
227 + 31471697 = 31471924
257 + 31471667 = 31471924
347 + 31471577 = 31471924

Showing the first eight; more decompositions exist.
