Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519938, here are decompositions:

31 + 33519907 = 33519938
61 + 33519877 = 33519938
211 + 33519727 = 33519938
229 + 33519709 = 33519938
349 + 33519589 = 33519938
379 + 33519559 = 33519938
541 + 33519397 = 33519938
769 + 33519169 = 33519938

Showing the first eight; more decompositions exist.
