Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618326, here are decompositions:

7 + 31618319 = 31618326
29 + 31618297 = 31618326
37 + 31618289 = 31618326
127 + 31618199 = 31618326
137 + 31618189 = 31618326
139 + 31618187 = 31618326
163 + 31618163 = 31618326
193 + 31618133 = 31618326

Showing the first eight; more decompositions exist.
