Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610598, here are decompositions:

11 + 31610587 = 31610598
17 + 31610581 = 31610598
29 + 31610569 = 31610598
37 + 31610561 = 31610598
59 + 31610539 = 31610598
79 + 31610519 = 31610598
281 + 31610317 = 31610598
307 + 31610291 = 31610598

Showing the first eight; more decompositions exist.
