Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619764, here are decompositions:

3 + 31619761 = 31619764
5 + 31619759 = 31619764
23 + 31619741 = 31619764
41 + 31619723 = 31619764
47 + 31619717 = 31619764
233 + 31619531 = 31619764
263 + 31619501 = 31619764
503 + 31619261 = 31619764

Showing the first eight; more decompositions exist.
