Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618452, here are decompositions:

11 + 31618441 = 31618452
29 + 31618423 = 31618452
43 + 31618409 = 31618452
163 + 31618289 = 31618452
241 + 31618211 = 31618452
263 + 31618189 = 31618452
331 + 31618121 = 31618452
353 + 31618099 = 31618452

Showing the first eight; more decompositions exist.
