Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516924, here are decompositions:

83 + 31516841 = 31516924
113 + 31516811 = 31516924
137 + 31516787 = 31516924
167 + 31516757 = 31516924
227 + 31516697 = 31516924
293 + 31516631 = 31516924
311 + 31516613 = 31516924
353 + 31516571 = 31516924

Showing the first eight; more decompositions exist.
