Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469732, here are decompositions:

43 + 31469689 = 31469732
61 + 31469671 = 31469732
79 + 31469653 = 31469732
103 + 31469629 = 31469732
109 + 31469623 = 31469732
163 + 31469569 = 31469732
379 + 31469353 = 31469732
409 + 31469323 = 31469732

Showing the first eight; more decompositions exist.
