Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606768, here are decompositions:

41 + 31606727 = 31606768
71 + 31606697 = 31606768
101 + 31606667 = 31606768
107 + 31606661 = 31606768
227 + 31606541 = 31606768
239 + 31606529 = 31606768
251 + 31606517 = 31606768
269 + 31606499 = 31606768

Showing the first eight; more decompositions exist.
