Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606750, here are decompositions:

23 + 31606727 = 31606750
47 + 31606703 = 31606750
53 + 31606697 = 31606750
59 + 31606691 = 31606750
83 + 31606667 = 31606750
89 + 31606661 = 31606750
107 + 31606643 = 31606750
167 + 31606583 = 31606750

Showing the first eight; more decompositions exist.
