Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560684, here are decompositions:

5 + 31560679 = 31560684
7 + 31560677 = 31560684
11 + 31560673 = 31560684
37 + 31560647 = 31560684
53 + 31560631 = 31560684
97 + 31560587 = 31560684
101 + 31560583 = 31560684
151 + 31560533 = 31560684

Showing the first eight; more decompositions exist.
