Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469354, here are decompositions:

31 + 31469323 = 31469354
61 + 31469293 = 31469354
67 + 31469287 = 31469354
157 + 31469197 = 31469354
211 + 31469143 = 31469354
223 + 31469131 = 31469354
313 + 31469041 = 31469354
577 + 31468777 = 31469354

Showing the first eight; more decompositions exist.
