Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516050, here are decompositions:

23 + 31516027 = 31516050
29 + 31516021 = 31516050
43 + 31516007 = 31516050
61 + 31515989 = 31516050
101 + 31515949 = 31516050
109 + 31515941 = 31516050
113 + 31515937 = 31516050
131 + 31515919 = 31516050

Showing the first eight; more decompositions exist.
