Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519820, here are decompositions:

29 + 33519791 = 33519820
71 + 33519749 = 33519820
197 + 33519623 = 33519820
281 + 33519539 = 33519820
293 + 33519527 = 33519820
401 + 33519419 = 33519820
449 + 33519371 = 33519820
479 + 33519341 = 33519820

Showing the first eight; more decompositions exist.
