Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516098, here are decompositions:

11 + 31516087 = 31516098
17 + 31516081 = 31516098
37 + 31516061 = 31516098
71 + 31516027 = 31516098
109 + 31515989 = 31516098
149 + 31515949 = 31516098
157 + 31515941 = 31516098
167 + 31515931 = 31516098

Showing the first eight; more decompositions exist.
