Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618294, here are decompositions:

5 + 31618289 = 31618294
83 + 31618211 = 31618294
101 + 31618193 = 31618294
107 + 31618187 = 31618294
131 + 31618163 = 31618294
167 + 31618127 = 31618294
173 + 31618121 = 31618294
233 + 31618061 = 31618294

Showing the first eight; more decompositions exist.
