Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618502, here are decompositions:

61 + 31618441 = 31618502
79 + 31618423 = 31618502
271 + 31618231 = 31618502
313 + 31618189 = 31618502
439 + 31618063 = 31618502
499 + 31618003 = 31618502
541 + 31617961 = 31618502
613 + 31617889 = 31618502

Showing the first eight; more decompositions exist.
