Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469810, here are decompositions:

13 + 31469797 = 31469810
79 + 31469731 = 31469810
139 + 31469671 = 31469810
157 + 31469653 = 31469810
181 + 31469629 = 31469810
223 + 31469587 = 31469810
241 + 31469569 = 31469810
283 + 31469527 = 31469810

Showing the first eight; more decompositions exist.
