Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533830, here are decompositions:

7 + 31533823 = 31533830
61 + 31533769 = 31533830
67 + 31533763 = 31533830
109 + 31533721 = 31533830
193 + 31533637 = 31533830
199 + 31533631 = 31533830
283 + 31533547 = 31533830
313 + 31533517 = 31533830

Showing the first eight; more decompositions exist.
