Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606466, here are decompositions:

37 + 31606429 = 31606466
43 + 31606423 = 31606466
79 + 31606387 = 31606466
97 + 31606369 = 31606466
127 + 31606339 = 31606466
379 + 31606087 = 31606466
643 + 31605823 = 31606466
709 + 31605757 = 31606466

Showing the first eight; more decompositions exist.
