Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607412, here are decompositions:

13 + 31607399 = 31607412
71 + 31607341 = 31607412
103 + 31607309 = 31607412
113 + 31607299 = 31607412
131 + 31607281 = 31607412
149 + 31607263 = 31607412
211 + 31607201 = 31607412
311 + 31607101 = 31607412

Showing the first eight; more decompositions exist.
