Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516062, here are decompositions:

41 + 31516021 = 31516062
73 + 31515989 = 31516062
113 + 31515949 = 31516062
131 + 31515931 = 31516062
163 + 31515899 = 31516062
181 + 31515881 = 31516062
241 + 31515821 = 31516062
293 + 31515769 = 31516062

Showing the first eight; more decompositions exist.
