Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469068, here are decompositions:

41 + 31469027 = 31469068
101 + 31468967 = 31469068
149 + 31468919 = 31469068
167 + 31468901 = 31469068
311 + 31468757 = 31469068
401 + 31468667 = 31469068
431 + 31468637 = 31469068
479 + 31468589 = 31469068

Showing the first eight; more decompositions exist.
