Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618054, here are decompositions:

5 + 31618049 = 31618054
11 + 31618043 = 31618054
53 + 31618001 = 31618054
101 + 31617953 = 31618054
113 + 31617941 = 31618054
191 + 31617863 = 31618054
227 + 31617827 = 31618054
257 + 31617797 = 31618054

Showing the first eight; more decompositions exist.
