Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533734, here are decompositions:

13 + 31533721 = 31533734
73 + 31533661 = 31533734
97 + 31533637 = 31533734
103 + 31533631 = 31533734
163 + 31533571 = 31533734
223 + 31533511 = 31533734
283 + 31533451 = 31533734
601 + 31533133 = 31533734

Showing the first eight; more decompositions exist.
