Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618276, here are decompositions:

83 + 31618193 = 31618276
89 + 31618187 = 31618276
113 + 31618163 = 31618276
149 + 31618127 = 31618276
227 + 31618049 = 31618276
233 + 31618043 = 31618276
317 + 31617959 = 31618276
449 + 31617827 = 31618276

Showing the first eight; more decompositions exist.
