Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533426, here are decompositions:

13 + 31533413 = 31533426
17 + 31533409 = 31533426
37 + 31533389 = 31533426
47 + 31533379 = 31533426
83 + 31533343 = 31533426
157 + 31533269 = 31533426
167 + 31533259 = 31533426
277 + 31533149 = 31533426

Showing the first eight; more decompositions exist.
