Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618350, here are decompositions:

31 + 31618319 = 31618350
53 + 31618297 = 31618350
61 + 31618289 = 31618350
139 + 31618211 = 31618350
151 + 31618199 = 31618350
157 + 31618193 = 31618350
163 + 31618187 = 31618350
223 + 31618127 = 31618350

Showing the first eight; more decompositions exist.
