Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566180, here are decompositions:

73 + 33566107 = 33566180
127 + 33566053 = 33566180
157 + 33566023 = 33566180
163 + 33566017 = 33566180
211 + 33565969 = 33566180
367 + 33565813 = 33566180
421 + 33565759 = 33566180
499 + 33565681 = 33566180

Showing the first eight; more decompositions exist.
