Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607736, here are decompositions:

19 + 31607717 = 31607736
47 + 31607689 = 31607736
53 + 31607683 = 31607736
107 + 31607629 = 31607736
137 + 31607599 = 31607736
157 + 31607579 = 31607736
233 + 31607503 = 31607736
263 + 31607473 = 31607736

Showing the first eight; more decompositions exist.
