Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469912, here are decompositions:

151 + 31469761 = 31469912
181 + 31469731 = 31469912
223 + 31469689 = 31469912
241 + 31469671 = 31469912
283 + 31469629 = 31469912
349 + 31469563 = 31469912
613 + 31469299 = 31469912
619 + 31469293 = 31469912

Showing the first eight; more decompositions exist.
