Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516052, here are decompositions:

31 + 31516021 = 31516052
103 + 31515949 = 31516052
283 + 31515769 = 31516052
349 + 31515703 = 31516052
751 + 31515301 = 31516052
769 + 31515283 = 31516052
811 + 31515241 = 31516052
859 + 31515193 = 31516052

Showing the first eight; more decompositions exist.
