Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469566, here are decompositions:

3 + 31469563 = 31469566
5 + 31469561 = 31469566
47 + 31469519 = 31469566
53 + 31469513 = 31469566
179 + 31469387 = 31469566
239 + 31469327 = 31469566
263 + 31469303 = 31469566
389 + 31469177 = 31469566

Showing the first eight; more decompositions exist.
