Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469492, here are decompositions:

139 + 31469353 = 31469492
193 + 31469299 = 31469492
199 + 31469293 = 31469492
283 + 31469209 = 31469492
349 + 31469143 = 31469492
499 + 31468993 = 31469492
631 + 31468861 = 31469492
643 + 31468849 = 31469492

Showing the first eight; more decompositions exist.
