Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613654, here are decompositions:

31 + 31613623 = 31613654
73 + 31613581 = 31613654
103 + 31613551 = 31613654
271 + 31613383 = 31613654
277 + 31613377 = 31613654
313 + 31613341 = 31613654
463 + 31613191 = 31613654
547 + 31613107 = 31613654

Showing the first eight; more decompositions exist.
