Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516082, here are decompositions:

61 + 31516021 = 31516082
151 + 31515931 = 31516082
163 + 31515919 = 31516082
313 + 31515769 = 31516082
349 + 31515733 = 31516082
379 + 31515703 = 31516082
523 + 31515559 = 31516082
811 + 31515271 = 31516082

Showing the first eight; more decompositions exist.
