Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612920, here are decompositions:

43 + 33612877 = 33612920
67 + 33612853 = 33612920
97 + 33612823 = 33612920
157 + 33612763 = 33612920
193 + 33612727 = 33612920
223 + 33612697 = 33612920
241 + 33612679 = 33612920
277 + 33612643 = 33612920

Showing the first eight; more decompositions exist.
