Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469188, here are decompositions:

11 + 31469177 = 31469188
269 + 31468919 = 31469188
431 + 31468757 = 31469188
461 + 31468727 = 31469188
521 + 31468667 = 31469188
557 + 31468631 = 31469188
599 + 31468589 = 31469188
617 + 31468571 = 31469188

Showing the first eight; more decompositions exist.
