Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468674, here are decompositions:

7 + 31468667 = 31468674
37 + 31468637 = 31468674
43 + 31468631 = 31468674
101 + 31468573 = 31468674
103 + 31468571 = 31468674
131 + 31468543 = 31468674
151 + 31468523 = 31468674
157 + 31468517 = 31468674

Showing the first eight; more decompositions exist.
