Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618396, here are decompositions:

107 + 31618289 = 31618396
197 + 31618199 = 31618396
233 + 31618163 = 31618396
263 + 31618133 = 31618396
269 + 31618127 = 31618396
347 + 31618049 = 31618396
353 + 31618043 = 31618396
443 + 31617953 = 31618396

Showing the first eight; more decompositions exist.
