Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516106, here are decompositions:

3 + 31516103 = 31516106
7 + 31516099 = 31516106
19 + 31516087 = 31516106
79 + 31516027 = 31516106
157 + 31515949 = 31516106
337 + 31515769 = 31516106
373 + 31515733 = 31516106
409 + 31515697 = 31516106

Showing the first eight; more decompositions exist.
