Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607460, here are decompositions:

11 + 31607449 = 31607460
13 + 31607447 = 31607460
37 + 31607423 = 31607460
61 + 31607399 = 31607460
97 + 31607363 = 31607460
103 + 31607357 = 31607460
151 + 31607309 = 31607460
163 + 31607297 = 31607460

Showing the first eight; more decompositions exist.
