Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618174, here are decompositions:

11 + 31618163 = 31618174
41 + 31618133 = 31618174
47 + 31618127 = 31618174
53 + 31618121 = 31618174
113 + 31618061 = 31618174
131 + 31618043 = 31618174
173 + 31618001 = 31618174
233 + 31617941 = 31618174

Showing the first eight; more decompositions exist.
