Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464144, here are decompositions:

7 + 31464137 = 31464144
83 + 31464061 = 31464144
97 + 31464047 = 31464144
113 + 31464031 = 31464144
181 + 31463963 = 31464144
223 + 31463921 = 31464144
233 + 31463911 = 31464144
251 + 31463893 = 31464144

Showing the first eight; more decompositions exist.
