Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618152, here are decompositions:

19 + 31618133 = 31618152
31 + 31618121 = 31618152
53 + 31618099 = 31618152
89 + 31618063 = 31618152
103 + 31618049 = 31618152
109 + 31618043 = 31618152
149 + 31618003 = 31618152
151 + 31618001 = 31618152

Showing the first eight; more decompositions exist.
