Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469618, here are decompositions:

31 + 31469587 = 31469618
151 + 31469467 = 31469618
211 + 31469407 = 31469618
331 + 31469287 = 31469618
379 + 31469239 = 31469618
409 + 31469209 = 31469618
421 + 31469197 = 31469618
487 + 31469131 = 31469618

Showing the first eight; more decompositions exist.
