Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469826, here are decompositions:

13 + 31469813 = 31469826
29 + 31469797 = 31469826
43 + 31469783 = 31469826
103 + 31469723 = 31469826
137 + 31469689 = 31469826
173 + 31469653 = 31469826
197 + 31469629 = 31469826
239 + 31469587 = 31469826

Showing the first eight; more decompositions exist.
