Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515114, here are decompositions:

41 + 31515073 = 31515114
47 + 31515067 = 31515114
67 + 31515047 = 31515114
73 + 31515041 = 31515114
107 + 31515007 = 31515114
151 + 31514963 = 31515114
167 + 31514947 = 31515114
181 + 31514933 = 31515114

Showing the first eight; more decompositions exist.
