Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451074, here are decompositions:

41 + 31451033 = 31451074
107 + 31450967 = 31451074
113 + 31450961 = 31451074
227 + 31450847 = 31451074
233 + 31450841 = 31451074
251 + 31450823 = 31451074
293 + 31450781 = 31451074
311 + 31450763 = 31451074

Showing the first eight; more decompositions exist.
