Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533854, here are decompositions:

7 + 31533847 = 31533854
31 + 31533823 = 31533854
193 + 31533661 = 31533854
223 + 31533631 = 31533854
241 + 31533613 = 31533854
283 + 31533571 = 31533854
307 + 31533547 = 31533854
337 + 31533517 = 31533854

Showing the first eight; more decompositions exist.
