Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618362, here are decompositions:

43 + 31618319 = 31618362
73 + 31618289 = 31618362
131 + 31618231 = 31618362
151 + 31618211 = 31618362
163 + 31618199 = 31618362
173 + 31618189 = 31618362
199 + 31618163 = 31618362
229 + 31618133 = 31618362

Showing the first eight; more decompositions exist.
