Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493840, here are decompositions:

11 + 33493829 = 33493840
167 + 33493673 = 33493840
227 + 33493613 = 33493840
239 + 33493601 = 33493840
311 + 33493529 = 33493840
449 + 33493391 = 33493840
467 + 33493373 = 33493840
557 + 33493283 = 33493840

Showing the first eight; more decompositions exist.
