Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606756, here are decompositions:

3 + 31606753 = 31606756
29 + 31606727 = 31606756
53 + 31606703 = 31606756
59 + 31606697 = 31606756
89 + 31606667 = 31606756
113 + 31606643 = 31606756
173 + 31606583 = 31606756
197 + 31606559 = 31606756

Showing the first eight; more decompositions exist.
