Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471830, here are decompositions:

19 + 33471811 = 33471830
31 + 33471799 = 33471830
61 + 33471769 = 33471830
97 + 33471733 = 33471830
109 + 33471721 = 33471830
163 + 33471667 = 33471830
181 + 33471649 = 33471830
277 + 33471553 = 33471830

Showing the first eight; more decompositions exist.
