Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556768, here are decompositions:

197 + 33556571 = 33556768
239 + 33556529 = 33556768
269 + 33556499 = 33556768
467 + 33556301 = 33556768
797 + 33555971 = 33556768
809 + 33555959 = 33556768
821 + 33555947 = 33556768
1031 + 33555737 = 33556768

Showing the first eight; more decompositions exist.
