Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468660, here are decompositions:

23 + 31468637 = 31468660
29 + 31468631 = 31468660
71 + 31468589 = 31468660
89 + 31468571 = 31468660
101 + 31468559 = 31468660
107 + 31468553 = 31468660
131 + 31468529 = 31468660
137 + 31468523 = 31468660

Showing the first eight; more decompositions exist.
