Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607648, here are decompositions:

19 + 31607629 = 31607648
67 + 31607581 = 31607648
97 + 31607551 = 31607648
199 + 31607449 = 31607648
307 + 31607341 = 31607648
349 + 31607299 = 31607648
367 + 31607281 = 31607648
421 + 31607227 = 31607648

Showing the first eight; more decompositions exist.
