Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607574, here are decompositions:

23 + 31607551 = 31607574
43 + 31607531 = 31607574
71 + 31607503 = 31607574
101 + 31607473 = 31607574
113 + 31607461 = 31607574
127 + 31607447 = 31607574
151 + 31607423 = 31607574
211 + 31607363 = 31607574

Showing the first eight; more decompositions exist.
