Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612680, here are decompositions:

7 + 33612673 = 33612680
37 + 33612643 = 33612680
97 + 33612583 = 33612680
163 + 33612517 = 33612680
193 + 33612487 = 33612680
223 + 33612457 = 33612680
271 + 33612409 = 33612680
349 + 33612331 = 33612680

Showing the first eight; more decompositions exist.
