Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607616, here are decompositions:

17 + 31607599 = 31607616
37 + 31607579 = 31607616
113 + 31607503 = 31607616
127 + 31607489 = 31607616
167 + 31607449 = 31607616
193 + 31607423 = 31607616
307 + 31607309 = 31607616
317 + 31607299 = 31607616

Showing the first eight; more decompositions exist.
