Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468654, here are decompositions:

17 + 31468637 = 31468654
23 + 31468631 = 31468654
83 + 31468571 = 31468654
101 + 31468553 = 31468654
131 + 31468523 = 31468654
137 + 31468517 = 31468654
251 + 31468403 = 31468654
257 + 31468397 = 31468654

Showing the first eight; more decompositions exist.
