Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607376, here are decompositions:

13 + 31607363 = 31607376
19 + 31607357 = 31607376
67 + 31607309 = 31607376
79 + 31607297 = 31607376
83 + 31607293 = 31607376
113 + 31607263 = 31607376
139 + 31607237 = 31607376
149 + 31607227 = 31607376

Showing the first eight; more decompositions exist.
