Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618466, here are decompositions:

3 + 31618463 = 31618466
43 + 31618423 = 31618466
277 + 31618189 = 31618466
367 + 31618099 = 31618466
409 + 31618057 = 31618466
463 + 31618003 = 31618466
499 + 31617967 = 31618466
577 + 31617889 = 31618466

Showing the first eight; more decompositions exist.
