Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618202, here are decompositions:

3 + 31618199 = 31618202
13 + 31618189 = 31618202
103 + 31618099 = 31618202
139 + 31618063 = 31618202
199 + 31618003 = 31618202
241 + 31617961 = 31618202
313 + 31617889 = 31618202
331 + 31617871 = 31618202

Showing the first eight; more decompositions exist.
