Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518114, here are decompositions:

53 + 31518061 = 31518114
83 + 31518031 = 31518114
107 + 31518007 = 31518114
113 + 31518001 = 31518114
151 + 31517963 = 31518114
163 + 31517951 = 31518114
227 + 31517887 = 31518114
263 + 31517851 = 31518114

Showing the first eight; more decompositions exist.
