Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618292, here are decompositions:

3 + 31618289 = 31618292
61 + 31618231 = 31618292
103 + 31618189 = 31618292
193 + 31618099 = 31618292
229 + 31618063 = 31618292
331 + 31617961 = 31618292
421 + 31617871 = 31618292
439 + 31617853 = 31618292

Showing the first eight; more decompositions exist.
