Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581828, here are decompositions:

37 + 33581791 = 33581828
61 + 33581767 = 33581828
67 + 33581761 = 33581828
151 + 33581677 = 33581828
157 + 33581671 = 33581828
211 + 33581617 = 33581828
229 + 33581599 = 33581828
307 + 33581521 = 33581828

Showing the first eight; more decompositions exist.
