Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516010, here are decompositions:

3 + 31516007 = 31516010
61 + 31515949 = 31516010
73 + 31515937 = 31516010
79 + 31515931 = 31516010
241 + 31515769 = 31516010
277 + 31515733 = 31516010
307 + 31515703 = 31516010
313 + 31515697 = 31516010

Showing the first eight; more decompositions exist.
