Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607364, here are decompositions:

7 + 31607357 = 31607364
23 + 31607341 = 31607364
37 + 31607327 = 31607364
67 + 31607297 = 31607364
71 + 31607293 = 31607364
73 + 31607291 = 31607364
83 + 31607281 = 31607364
101 + 31607263 = 31607364

Showing the first eight; more decompositions exist.
