Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469852, here are decompositions:

3 + 31469849 = 31469852
163 + 31469689 = 31469852
181 + 31469671 = 31469852
199 + 31469653 = 31469852
223 + 31469629 = 31469852
229 + 31469623 = 31469852
283 + 31469569 = 31469852
409 + 31469443 = 31469852

Showing the first eight; more decompositions exist.
