Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516058, here are decompositions:

31 + 31516027 = 31516058
37 + 31516021 = 31516058
109 + 31515949 = 31516058
127 + 31515931 = 31516058
139 + 31515919 = 31516058
499 + 31515559 = 31516058
751 + 31515307 = 31516058
757 + 31515301 = 31516058

Showing the first eight; more decompositions exist.
