Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618446, here are decompositions:

5 + 31618441 = 31618446
23 + 31618423 = 31618446
37 + 31618409 = 31618446
43 + 31618403 = 31618446
127 + 31618319 = 31618446
149 + 31618297 = 31618446
157 + 31618289 = 31618446
257 + 31618189 = 31618446

Showing the first eight; more decompositions exist.
