Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610836, here are decompositions:

107 + 31610729 = 31610836
113 + 31610723 = 31610836
197 + 31610639 = 31610836
263 + 31610573 = 31610836
317 + 31610519 = 31610836
443 + 31610393 = 31610836
503 + 31610333 = 31610836
557 + 31610279 = 31610836

Showing the first eight; more decompositions exist.
