Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610758, here are decompositions:

17 + 31610741 = 31610758
29 + 31610729 = 31610758
197 + 31610561 = 31610758
239 + 31610519 = 31610758
419 + 31610339 = 31610758
467 + 31610291 = 31610758
479 + 31610279 = 31610758
521 + 31610237 = 31610758

Showing the first eight; more decompositions exist.
