Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607360, here are decompositions:

3 + 31607357 = 31607360
19 + 31607341 = 31607360
61 + 31607299 = 31607360
67 + 31607293 = 31607360
79 + 31607281 = 31607360
97 + 31607263 = 31607360
223 + 31607137 = 31607360
313 + 31607047 = 31607360

Showing the first eight; more decompositions exist.
