Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555672, here are decompositions:

5 + 33555667 = 33555672
11 + 33555661 = 33555672
13 + 33555659 = 33555672
43 + 33555629 = 33555672
61 + 33555611 = 33555672
89 + 33555583 = 33555672
109 + 33555563 = 33555672
173 + 33555499 = 33555672

Showing the first eight; more decompositions exist.
