Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612764, here are decompositions:

5 + 31612759 = 31612764
11 + 31612753 = 31612764
17 + 31612747 = 31612764
31 + 31612733 = 31612764
37 + 31612727 = 31612764
97 + 31612667 = 31612764
101 + 31612663 = 31612764
103 + 31612661 = 31612764

Showing the first eight; more decompositions exist.
