Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479310, here are decompositions:

3 + 31479307 = 31479310
11 + 31479299 = 31479310
41 + 31479269 = 31479310
59 + 31479251 = 31479310
113 + 31479197 = 31479310
179 + 31479131 = 31479310
227 + 31479083 = 31479310
293 + 31479017 = 31479310

Showing the first eight; more decompositions exist.
