Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469042, here are decompositions:

79 + 31468963 = 31469042
139 + 31468903 = 31469042
181 + 31468861 = 31469042
193 + 31468849 = 31469042
499 + 31468543 = 31469042
571 + 31468471 = 31469042
643 + 31468399 = 31469042
673 + 31468369 = 31469042

Showing the first eight; more decompositions exist.
