Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469308, here are decompositions:

5 + 31469303 = 31469308
29 + 31469279 = 31469308
131 + 31469177 = 31469308
239 + 31469069 = 31469308
281 + 31469027 = 31469308
389 + 31468919 = 31469308
641 + 31468667 = 31469308
677 + 31468631 = 31469308

Showing the first eight; more decompositions exist.
