Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464156, here are decompositions:

7 + 31464149 = 31464156
13 + 31464143 = 31464156
19 + 31464137 = 31464156
89 + 31464067 = 31464156
109 + 31464047 = 31464156
193 + 31463963 = 31464156
197 + 31463959 = 31464156
263 + 31463893 = 31464156

Showing the first eight; more decompositions exist.
