Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607482, here are decompositions:

59 + 31607423 = 31607482
83 + 31607399 = 31607482
173 + 31607309 = 31607482
191 + 31607291 = 31607482
281 + 31607201 = 31607482
443 + 31607039 = 31607482
503 + 31606979 = 31607482
509 + 31606973 = 31607482

Showing the first eight; more decompositions exist.
