Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618426, here are decompositions:

3 + 31618423 = 31618426
17 + 31618409 = 31618426
23 + 31618403 = 31618426
107 + 31618319 = 31618426
137 + 31618289 = 31618426
227 + 31618199 = 31618426
233 + 31618193 = 31618426
239 + 31618187 = 31618426

Showing the first eight; more decompositions exist.
