Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469358, here are decompositions:

5 + 31469353 = 31469358
31 + 31469327 = 31469358
59 + 31469299 = 31469358
71 + 31469287 = 31469358
79 + 31469279 = 31469358
149 + 31469209 = 31469358
181 + 31469177 = 31469358
227 + 31469131 = 31469358

Showing the first eight; more decompositions exist.
