Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516714, here are decompositions:

11 + 31516703 = 31516714
17 + 31516697 = 31516714
83 + 31516631 = 31516714
101 + 31516613 = 31516714
191 + 31516523 = 31516714
353 + 31516361 = 31516714
461 + 31516253 = 31516714
557 + 31516157 = 31516714

Showing the first eight; more decompositions exist.
