Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469314, here are decompositions:

11 + 31469303 = 31469314
137 + 31469177 = 31469314
281 + 31469033 = 31469314
347 + 31468967 = 31469314
491 + 31468823 = 31469314
521 + 31468793 = 31469314
557 + 31468757 = 31469314
587 + 31468727 = 31469314

Showing the first eight; more decompositions exist.
