Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460356, here are decompositions:

17 + 31460339 = 31460356
89 + 31460267 = 31460356
227 + 31460129 = 31460356
293 + 31460063 = 31460356
419 + 31459937 = 31460356
503 + 31459853 = 31460356
509 + 31459847 = 31460356
647 + 31459709 = 31460356

Showing the first eight; more decompositions exist.
