Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606966, here are decompositions:

3 + 31606963 = 31606966
23 + 31606943 = 31606966
47 + 31606919 = 31606966
137 + 31606829 = 31606966
239 + 31606727 = 31606966
263 + 31606703 = 31606966
269 + 31606697 = 31606966
383 + 31606583 = 31606966

Showing the first eight; more decompositions exist.
