Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560696, here are decompositions:

7 + 31560689 = 31560696
17 + 31560679 = 31560696
19 + 31560677 = 31560696
23 + 31560673 = 31560696
67 + 31560629 = 31560696
107 + 31560589 = 31560696
109 + 31560587 = 31560696
113 + 31560583 = 31560696

Showing the first eight; more decompositions exist.
