Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610672, here are decompositions:

31 + 31610641 = 31610672
43 + 31610629 = 31610672
103 + 31610569 = 31610672
109 + 31610563 = 31610672
151 + 31610521 = 31610672
283 + 31610389 = 31610672
661 + 31610011 = 31610672
739 + 31609933 = 31610672

Showing the first eight; more decompositions exist.
