Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516046, here are decompositions:

19 + 31516027 = 31516046
97 + 31515949 = 31516046
109 + 31515937 = 31516046
127 + 31515919 = 31516046
277 + 31515769 = 31516046
283 + 31515763 = 31516046
313 + 31515733 = 31516046
349 + 31515697 = 31516046

Showing the first eight; more decompositions exist.
