Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533998, here are decompositions:

19 + 31533979 = 31533998
31 + 31533967 = 31533998
79 + 31533919 = 31533998
127 + 31533871 = 31533998
151 + 31533847 = 31533998
229 + 31533769 = 31533998
277 + 31533721 = 31533998
337 + 31533661 = 31533998

Showing the first eight; more decompositions exist.
