Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464066, here are decompositions:

5 + 31464061 = 31464066
19 + 31464047 = 31464066
103 + 31463963 = 31464066
107 + 31463959 = 31464066
157 + 31463909 = 31464066
173 + 31463893 = 31464066
223 + 31463843 = 31464066
239 + 31463827 = 31464066

Showing the first eight; more decompositions exist.
