Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479324, here are decompositions:

17 + 31479307 = 31479324
47 + 31479277 = 31479324
53 + 31479271 = 31479324
73 + 31479251 = 31479324
83 + 31479241 = 31479324
127 + 31479197 = 31479324
193 + 31479131 = 31479324
197 + 31479127 = 31479324

Showing the first eight; more decompositions exist.
