Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607848, here are decompositions:

17 + 31607831 = 31607848
59 + 31607789 = 31607848
101 + 31607747 = 31607848
131 + 31607717 = 31607848
269 + 31607579 = 31607848
317 + 31607531 = 31607848
359 + 31607489 = 31607848
401 + 31607447 = 31607848

Showing the first eight; more decompositions exist.
