Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613460, here are decompositions:

19 + 31613441 = 31613460
23 + 31613437 = 31613460
59 + 31613401 = 31613460
61 + 31613399 = 31613460
83 + 31613377 = 31613460
103 + 31613357 = 31613460
127 + 31613333 = 31613460
211 + 31613249 = 31613460

Showing the first eight; more decompositions exist.
