Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460446, here are decompositions:

5 + 31460441 = 31460446
47 + 31460399 = 31460446
107 + 31460339 = 31460446
167 + 31460279 = 31460446
179 + 31460267 = 31460446
317 + 31460129 = 31460446
383 + 31460063 = 31460446
509 + 31459937 = 31460446

Showing the first eight; more decompositions exist.
