Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618334, here are decompositions:

37 + 31618297 = 31618334
103 + 31618231 = 31618334
271 + 31618063 = 31618334
277 + 31618057 = 31618334
331 + 31618003 = 31618334
337 + 31617997 = 31618334
367 + 31617967 = 31618334
373 + 31617961 = 31618334

Showing the first eight; more decompositions exist.
