Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607434, here are decompositions:

11 + 31607423 = 31607434
71 + 31607363 = 31607434
107 + 31607327 = 31607434
137 + 31607297 = 31607434
197 + 31607237 = 31607434
227 + 31607207 = 31607434
233 + 31607201 = 31607434
281 + 31607153 = 31607434

Showing the first eight; more decompositions exist.
