Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612572, here are decompositions:

13 + 33612559 = 33612572
139 + 33612433 = 33612572
163 + 33612409 = 33612572
241 + 33612331 = 33612572
283 + 33612289 = 33612572
373 + 33612199 = 33612572
421 + 33612151 = 33612572
463 + 33612109 = 33612572

Showing the first eight; more decompositions exist.
