Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610668, here are decompositions:

29 + 31610639 = 31610668
107 + 31610561 = 31610668
149 + 31610519 = 31610668
389 + 31610279 = 31610668
431 + 31610237 = 31610668
587 + 31610081 = 31610668
659 + 31610009 = 31610668
701 + 31609967 = 31610668

Showing the first eight; more decompositions exist.
