Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610998, here are decompositions:

131 + 31610867 = 31610998
227 + 31610771 = 31610998
257 + 31610741 = 31610998
269 + 31610729 = 31610998
359 + 31610639 = 31610998
479 + 31610519 = 31610998
659 + 31610339 = 31610998
719 + 31610279 = 31610998

Showing the first eight; more decompositions exist.
