Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469756, here are decompositions:

67 + 31469689 = 31469756
103 + 31469653 = 31469756
127 + 31469629 = 31469756
193 + 31469563 = 31469756
229 + 31469527 = 31469756
313 + 31469443 = 31469756
349 + 31469407 = 31469756
433 + 31469323 = 31469756

Showing the first eight; more decompositions exist.
