Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469122, here are decompositions:

53 + 31469069 = 31469122
89 + 31469033 = 31469122
491 + 31468631 = 31469122
563 + 31468559 = 31469122
569 + 31468553 = 31469122
593 + 31468529 = 31469122
599 + 31468523 = 31469122
719 + 31468403 = 31469122

Showing the first eight; more decompositions exist.
