Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469084, here are decompositions:

43 + 31469041 = 31469084
181 + 31468903 = 31469084
223 + 31468861 = 31469084
307 + 31468777 = 31469084
487 + 31468597 = 31469084
541 + 31468543 = 31469084
613 + 31468471 = 31469084
631 + 31468453 = 31469084

Showing the first eight; more decompositions exist.
