Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469374, here are decompositions:

17 + 31469357 = 31469374
47 + 31469327 = 31469374
71 + 31469303 = 31469374
197 + 31469177 = 31469374
347 + 31469027 = 31469374
617 + 31468757 = 31469374
647 + 31468727 = 31469374
743 + 31468631 = 31469374

Showing the first eight; more decompositions exist.
