Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564820, here are decompositions:

53 + 33564767 = 33564820
59 + 33564761 = 33564820
83 + 33564737 = 33564820
89 + 33564731 = 33564820
167 + 33564653 = 33564820
269 + 33564551 = 33564820
461 + 33564359 = 33564820
467 + 33564353 = 33564820

Showing the first eight; more decompositions exist.
