Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606964, here are decompositions:

7 + 31606957 = 31606964
13 + 31606951 = 31606964
61 + 31606903 = 31606964
211 + 31606753 = 31606964
223 + 31606741 = 31606964
283 + 31606681 = 31606964
307 + 31606657 = 31606964
313 + 31606651 = 31606964

Showing the first eight; more decompositions exist.
