Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533968, here are decompositions:

19 + 31533949 = 31533968
97 + 31533871 = 31533968
139 + 31533829 = 31533968
199 + 31533769 = 31533968
307 + 31533661 = 31533968
331 + 31533637 = 31533968
337 + 31533631 = 31533968
397 + 31533571 = 31533968

Showing the first eight; more decompositions exist.
