Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469332, here are decompositions:

5 + 31469327 = 31469332
29 + 31469303 = 31469332
53 + 31469279 = 31469332
263 + 31469069 = 31469332
431 + 31468901 = 31469332
509 + 31468823 = 31469332
701 + 31468631 = 31469332
743 + 31468589 = 31469332

Showing the first eight; more decompositions exist.
