Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581928, here are decompositions:

7 + 33581921 = 33581928
59 + 33581869 = 33581928
67 + 33581861 = 33581928
71 + 33581857 = 33581928
109 + 33581819 = 33581928
137 + 33581791 = 33581928
167 + 33581761 = 33581928
241 + 33581687 = 33581928

Showing the first eight; more decompositions exist.
