Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610646, here are decompositions:

5 + 31610641 = 31610646
7 + 31610639 = 31610646
17 + 31610629 = 31610646
59 + 31610587 = 31610646
73 + 31610573 = 31610646
83 + 31610563 = 31610646
107 + 31610539 = 31610646
127 + 31610519 = 31610646

Showing the first eight; more decompositions exist.
