Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469392, here are decompositions:

5 + 31469387 = 31469392
89 + 31469303 = 31469392
113 + 31469279 = 31469392
359 + 31469033 = 31469392
491 + 31468901 = 31469392
569 + 31468823 = 31469392
599 + 31468793 = 31469392
761 + 31468631 = 31469392

Showing the first eight; more decompositions exist.
