Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581784, here are decompositions:

17 + 33581767 = 33581784
23 + 33581761 = 33581784
43 + 33581741 = 33581784
97 + 33581687 = 33581784
107 + 33581677 = 33581784
113 + 33581671 = 33581784
163 + 33581621 = 33581784
167 + 33581617 = 33581784

Showing the first eight; more decompositions exist.
