Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607550, here are decompositions:

19 + 31607531 = 31607550
47 + 31607503 = 31607550
61 + 31607489 = 31607550
89 + 31607461 = 31607550
101 + 31607449 = 31607550
103 + 31607447 = 31607550
127 + 31607423 = 31607550
151 + 31607399 = 31607550

Showing the first eight; more decompositions exist.
