Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460584, here are decompositions:

3 + 31460581 = 31460584
47 + 31460537 = 31460584
101 + 31460483 = 31460584
263 + 31460321 = 31460584
293 + 31460291 = 31460584
317 + 31460267 = 31460584
521 + 31460063 = 31460584
647 + 31459937 = 31460584

Showing the first eight; more decompositions exist.
