Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618376, here are decompositions:

79 + 31618297 = 31618376
277 + 31618099 = 31618376
313 + 31618063 = 31618376
373 + 31618003 = 31618376
379 + 31617997 = 31618376
409 + 31617967 = 31618376
487 + 31617889 = 31618376
499 + 31617877 = 31618376

Showing the first eight; more decompositions exist.
