Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464078, here are decompositions:

11 + 31464067 = 31464078
17 + 31464061 = 31464078
31 + 31464047 = 31464078
47 + 31464031 = 31464078
137 + 31463941 = 31464078
157 + 31463921 = 31464078
167 + 31463911 = 31464078
181 + 31463897 = 31464078

Showing the first eight; more decompositions exist.
