Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505520, here are decompositions:

73 + 33505447 = 33505520
79 + 33505441 = 33505520
127 + 33505393 = 33505520
157 + 33505363 = 33505520
211 + 33505309 = 33505520
397 + 33505123 = 33505520
463 + 33505057 = 33505520
733 + 33504787 = 33505520

Showing the first eight; more decompositions exist.
