Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469126, here are decompositions:

163 + 31468963 = 31469126
223 + 31468903 = 31469126
277 + 31468849 = 31469126
349 + 31468777 = 31469126
673 + 31468453 = 31469126
727 + 31468399 = 31469126
757 + 31468369 = 31469126
883 + 31468243 = 31469126

Showing the first eight; more decompositions exist.
