Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618196, here are decompositions:

3 + 31618193 = 31618196
7 + 31618189 = 31618196
97 + 31618099 = 31618196
139 + 31618057 = 31618196
193 + 31618003 = 31618196
199 + 31617997 = 31618196
229 + 31617967 = 31618196
307 + 31617889 = 31618196

Showing the first eight; more decompositions exist.
