Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606764, here are decompositions:

11 + 31606753 = 31606764
23 + 31606741 = 31606764
37 + 31606727 = 31606764
53 + 31606711 = 31606764
61 + 31606703 = 31606764
67 + 31606697 = 31606764
73 + 31606691 = 31606764
83 + 31606681 = 31606764

Showing the first eight; more decompositions exist.
