Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540716, here are decompositions:

7 + 31540709 = 31540716
17 + 31540699 = 31540716
23 + 31540693 = 31540716
37 + 31540679 = 31540716
47 + 31540669 = 31540716
59 + 31540657 = 31540716
73 + 31540643 = 31540716
79 + 31540637 = 31540716

Showing the first eight; more decompositions exist.
