Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33565572, here are decompositions:

13 + 33565559 = 33565572
31 + 33565541 = 33565572
83 + 33565489 = 33565572
199 + 33565373 = 33565572
233 + 33565339 = 33565572
239 + 33565333 = 33565572
349 + 33565223 = 33565572
373 + 33565199 = 33565572

Showing the first eight; more decompositions exist.
