Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607662, here are decompositions:

83 + 31607579 = 31607662
131 + 31607531 = 31607662
173 + 31607489 = 31607662
239 + 31607423 = 31607662
263 + 31607399 = 31607662
353 + 31607309 = 31607662
461 + 31607201 = 31607662
509 + 31607153 = 31607662

Showing the first eight; more decompositions exist.
