Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607366, here are decompositions:

3 + 31607363 = 31607366
67 + 31607299 = 31607366
73 + 31607293 = 31607366
103 + 31607263 = 31607366
139 + 31607227 = 31607366
229 + 31607137 = 31607366
409 + 31606957 = 31607366
463 + 31606903 = 31607366

Showing the first eight; more decompositions exist.
