Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469362, here are decompositions:

5 + 31469357 = 31469362
59 + 31469303 = 31469362
83 + 31469279 = 31469362
293 + 31469069 = 31469362
443 + 31468919 = 31469362
461 + 31468901 = 31469362
569 + 31468793 = 31469362
773 + 31468589 = 31469362

Showing the first eight; more decompositions exist.
