Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479584, here are decompositions:

7 + 31479577 = 31479584
43 + 31479541 = 31479584
67 + 31479517 = 31479584
127 + 31479457 = 31479584
163 + 31479421 = 31479584
277 + 31479307 = 31479584
307 + 31479277 = 31479584
313 + 31479271 = 31479584

Showing the first eight; more decompositions exist.
