Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469080, here are decompositions:

11 + 31469069 = 31469080
47 + 31469033 = 31469080
53 + 31469027 = 31469080
113 + 31468967 = 31469080
179 + 31468901 = 31469080
257 + 31468823 = 31469080
353 + 31468727 = 31469080
443 + 31468637 = 31469080

Showing the first eight; more decompositions exist.
