Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533800, here are decompositions:

31 + 31533769 = 31533800
37 + 31533763 = 31533800
79 + 31533721 = 31533800
139 + 31533661 = 31533800
163 + 31533637 = 31533800
229 + 31533571 = 31533800
283 + 31533517 = 31533800
349 + 31533451 = 31533800

Showing the first eight; more decompositions exist.
