Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469624, here are decompositions:

3 + 31469621 = 31469624
37 + 31469587 = 31469624
61 + 31469563 = 31469624
97 + 31469527 = 31469624
157 + 31469467 = 31469624
181 + 31469443 = 31469624
271 + 31469353 = 31469624
331 + 31469293 = 31469624

Showing the first eight; more decompositions exist.
