Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505856, here are decompositions:

3 + 33505853 = 33505856
67 + 33505789 = 33505856
79 + 33505777 = 33505856
193 + 33505663 = 33505856
277 + 33505579 = 33505856
283 + 33505573 = 33505856
313 + 33505543 = 33505856
337 + 33505519 = 33505856

Showing the first eight; more decompositions exist.
