Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469660, here are decompositions:

7 + 31469653 = 31469660
31 + 31469629 = 31469660
37 + 31469623 = 31469660
73 + 31469587 = 31469660
97 + 31469563 = 31469660
193 + 31469467 = 31469660
307 + 31469353 = 31469660
337 + 31469323 = 31469660

Showing the first eight; more decompositions exist.
