Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533836, here are decompositions:

3 + 31533833 = 31533836
7 + 31533829 = 31533836
13 + 31533823 = 31533836
67 + 31533769 = 31533836
73 + 31533763 = 31533836
199 + 31533637 = 31533836
223 + 31533613 = 31533836
337 + 31533499 = 31533836

Showing the first eight; more decompositions exist.
