Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469512, here are decompositions:

71 + 31469441 = 31469512
89 + 31469423 = 31469512
101 + 31469411 = 31469512
233 + 31469279 = 31469512
443 + 31469069 = 31469512
479 + 31469033 = 31469512
593 + 31468919 = 31469512
719 + 31468793 = 31469512

Showing the first eight; more decompositions exist.
