Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606722, here are decompositions:

11 + 31606711 = 31606722
19 + 31606703 = 31606722
31 + 31606691 = 31606722
41 + 31606681 = 31606722
61 + 31606661 = 31606722
71 + 31606651 = 31606722
79 + 31606643 = 31606722
139 + 31606583 = 31606722

Showing the first eight; more decompositions exist.
