Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464586, here are decompositions:

5 + 31464581 = 31464586
29 + 31464557 = 31464586
227 + 31464359 = 31464586
317 + 31464269 = 31464586
353 + 31464233 = 31464586
443 + 31464143 = 31464586
449 + 31464137 = 31464586
677 + 31463909 = 31464586

Showing the first eight; more decompositions exist.
