Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610626, here are decompositions:

53 + 31610573 = 31610626
107 + 31610519 = 31610626
233 + 31610393 = 31610626
263 + 31610363 = 31610626
293 + 31610333 = 31610626
347 + 31610279 = 31610626
389 + 31610237 = 31610626
563 + 31610063 = 31610626

Showing the first eight; more decompositions exist.
