Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610746, here are decompositions:

5 + 31610741 = 31610746
17 + 31610729 = 31610746
23 + 31610723 = 31610746
107 + 31610639 = 31610746
173 + 31610573 = 31610746
227 + 31610519 = 31610746
353 + 31610393 = 31610746
383 + 31610363 = 31610746

Showing the first eight; more decompositions exist.
