Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533674, here are decompositions:

13 + 31533661 = 31533674
37 + 31533637 = 31533674
43 + 31533631 = 31533674
61 + 31533613 = 31533674
103 + 31533571 = 31533674
127 + 31533547 = 31533674
157 + 31533517 = 31533674
163 + 31533511 = 31533674

Showing the first eight; more decompositions exist.
