Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469078, here are decompositions:

37 + 31469041 = 31469078
229 + 31468849 = 31469078
379 + 31468699 = 31469078
607 + 31468471 = 31469078
631 + 31468447 = 31469078
709 + 31468369 = 31469078
877 + 31468201 = 31469078
919 + 31468159 = 31469078

Showing the first eight; more decompositions exist.
