Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493760, here are decompositions:

43 + 33493717 = 33493760
67 + 33493693 = 33493760
193 + 33493567 = 33493760
211 + 33493549 = 33493760
277 + 33493483 = 33493760
373 + 33493387 = 33493760
397 + 33493363 = 33493760
439 + 33493321 = 33493760

Showing the first eight; more decompositions exist.
