Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533884, here are decompositions:

13 + 31533871 = 31533884
37 + 31533847 = 31533884
61 + 31533823 = 31533884
163 + 31533721 = 31533884
223 + 31533661 = 31533884
271 + 31533613 = 31533884
313 + 31533571 = 31533884
337 + 31533547 = 31533884

Showing the first eight; more decompositions exist.
