Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607468, here are decompositions:

7 + 31607461 = 31607468
19 + 31607449 = 31607468
127 + 31607341 = 31607468
241 + 31607227 = 31607468
331 + 31607137 = 31607468
367 + 31607101 = 31607468
421 + 31607047 = 31607468
727 + 31606741 = 31607468

Showing the first eight; more decompositions exist.
