Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618454, here are decompositions:

13 + 31618441 = 31618454
31 + 31618423 = 31618454
157 + 31618297 = 31618454
223 + 31618231 = 31618454
397 + 31618057 = 31618454
457 + 31617997 = 31618454
487 + 31617967 = 31618454
577 + 31617877 = 31618454

Showing the first eight; more decompositions exist.
