Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469656, here are decompositions:

3 + 31469653 = 31469656
137 + 31469519 = 31469656
233 + 31469423 = 31469656
269 + 31469387 = 31469656
353 + 31469303 = 31469656
479 + 31469177 = 31469656
587 + 31469069 = 31469656
863 + 31468793 = 31469656

Showing the first eight; more decompositions exist.
