Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610790, here are decompositions:

11 + 31610779 = 31610790
17 + 31610773 = 31610790
19 + 31610771 = 31610790
61 + 31610729 = 31610790
67 + 31610723 = 31610790
83 + 31610707 = 31610790
149 + 31610641 = 31610790
151 + 31610639 = 31610790

Showing the first eight; more decompositions exist.
