Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479264, here are decompositions:

13 + 31479251 = 31479264
23 + 31479241 = 31479264
67 + 31479197 = 31479264
137 + 31479127 = 31479264
163 + 31479101 = 31479264
181 + 31479083 = 31479264
191 + 31479073 = 31479264
233 + 31479031 = 31479264

Showing the first eight; more decompositions exist.
