Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510074, here are decompositions:

53 + 31510021 = 31510074
67 + 31510007 = 31510074
73 + 31510001 = 31510074
83 + 31509991 = 31510074
103 + 31509971 = 31510074
107 + 31509967 = 31510074
181 + 31509893 = 31510074
191 + 31509883 = 31510074

Showing the first eight; more decompositions exist.
