Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469072, here are decompositions:

3 + 31469069 = 31469072
31 + 31469041 = 31469072
79 + 31468993 = 31469072
109 + 31468963 = 31469072
211 + 31468861 = 31469072
223 + 31468849 = 31469072
373 + 31468699 = 31469072
499 + 31468573 = 31469072

Showing the first eight; more decompositions exist.
