Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618344, here are decompositions:

47 + 31618297 = 31618344
113 + 31618231 = 31618344
151 + 31618193 = 31618344
157 + 31618187 = 31618344
181 + 31618163 = 31618344
211 + 31618133 = 31618344
223 + 31618121 = 31618344
281 + 31618063 = 31618344

Showing the first eight; more decompositions exist.
