Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618082, here are decompositions:

19 + 31618063 = 31618082
79 + 31618003 = 31618082
193 + 31617889 = 31618082
211 + 31617871 = 31618082
229 + 31617853 = 31618082
271 + 31617811 = 31618082
409 + 31617673 = 31618082
499 + 31617583 = 31618082

Showing the first eight; more decompositions exist.
