Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479534, here are decompositions:

17 + 31479517 = 31479534
43 + 31479491 = 31479534
67 + 31479467 = 31479534
113 + 31479421 = 31479534
197 + 31479337 = 31479534
227 + 31479307 = 31479534
257 + 31479277 = 31479534
263 + 31479271 = 31479534

Showing the first eight; more decompositions exist.
