Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468726, here are decompositions:

59 + 31468667 = 31468726
89 + 31468637 = 31468726
137 + 31468589 = 31468726
167 + 31468559 = 31468726
173 + 31468553 = 31468726
197 + 31468529 = 31468726
227 + 31468499 = 31468726
389 + 31468337 = 31468726

Showing the first eight; more decompositions exist.
