Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618522, here are decompositions:

3 + 31618519 = 31618522
59 + 31618463 = 31618522
113 + 31618409 = 31618522
233 + 31618289 = 31618522
311 + 31618211 = 31618522
359 + 31618163 = 31618522
389 + 31618133 = 31618522
401 + 31618121 = 31618522

Showing the first eight; more decompositions exist.
