Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469344, here are decompositions:

17 + 31469327 = 31469344
41 + 31469303 = 31469344
167 + 31469177 = 31469344
311 + 31469033 = 31469344
317 + 31469027 = 31469344
443 + 31468901 = 31469344
521 + 31468823 = 31469344
587 + 31468757 = 31469344

Showing the first eight; more decompositions exist.
