Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521780, here are decompositions:

67 + 33521713 = 33521780
79 + 33521701 = 33521780
151 + 33521629 = 33521780
157 + 33521623 = 33521780
241 + 33521539 = 33521780
349 + 33521431 = 33521780
379 + 33521401 = 33521780
601 + 33521179 = 33521780

Showing the first eight; more decompositions exist.
