Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479548, here are decompositions:

7 + 31479541 = 31479548
31 + 31479517 = 31479548
109 + 31479439 = 31479548
127 + 31479421 = 31479548
211 + 31479337 = 31479548
241 + 31479307 = 31479548
271 + 31479277 = 31479548
277 + 31479271 = 31479548

Showing the first eight; more decompositions exist.
