Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479546, here are decompositions:

5 + 31479541 = 31479546
29 + 31479517 = 31479546
47 + 31479499 = 31479546
79 + 31479467 = 31479546
89 + 31479457 = 31479546
107 + 31479439 = 31479546
127 + 31479419 = 31479546
239 + 31479307 = 31479546

Showing the first eight; more decompositions exist.
