Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469846, here are decompositions:

157 + 31469689 = 31469846
193 + 31469653 = 31469846
223 + 31469623 = 31469846
277 + 31469569 = 31469846
283 + 31469563 = 31469846
379 + 31469467 = 31469846
439 + 31469407 = 31469846
523 + 31469323 = 31469846

Showing the first eight; more decompositions exist.
