Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618064, here are decompositions:

3 + 31618061 = 31618064
7 + 31618057 = 31618064
61 + 31618003 = 31618064
67 + 31617997 = 31618064
97 + 31617967 = 31618064
103 + 31617961 = 31618064
193 + 31617871 = 31618064
211 + 31617853 = 31618064

Showing the first eight; more decompositions exist.
