Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533654, here are decompositions:

13 + 31533641 = 31533654
17 + 31533637 = 31533654
23 + 31533631 = 31533654
41 + 31533613 = 31533654
43 + 31533611 = 31533654
67 + 31533587 = 31533654
73 + 31533581 = 31533654
83 + 31533571 = 31533654

Showing the first eight; more decompositions exist.
