Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618246, here are decompositions:

47 + 31618199 = 31618246
53 + 31618193 = 31618246
59 + 31618187 = 31618246
83 + 31618163 = 31618246
113 + 31618133 = 31618246
197 + 31618049 = 31618246
293 + 31617953 = 31618246
347 + 31617899 = 31618246

Showing the first eight; more decompositions exist.
