Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618262, here are decompositions:

31 + 31618231 = 31618262
73 + 31618189 = 31618262
163 + 31618099 = 31618262
199 + 31618063 = 31618262
373 + 31617889 = 31618262
409 + 31617853 = 31618262
499 + 31617763 = 31618262
631 + 31617631 = 31618262

Showing the first eight; more decompositions exist.
