Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469224, here are decompositions:

47 + 31469177 = 31469224
191 + 31469033 = 31469224
197 + 31469027 = 31469224
257 + 31468967 = 31469224
401 + 31468823 = 31469224
431 + 31468793 = 31469224
467 + 31468757 = 31469224
557 + 31468667 = 31469224

Showing the first eight; more decompositions exist.
