Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469038, here are decompositions:

5 + 31469033 = 31469038
11 + 31469027 = 31469038
71 + 31468967 = 31469038
137 + 31468901 = 31469038
281 + 31468757 = 31469038
311 + 31468727 = 31469038
401 + 31468637 = 31469038
449 + 31468589 = 31469038

Showing the first eight; more decompositions exist.
