Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555320, here are decompositions:

3 + 33555317 = 33555320
31 + 33555289 = 33555320
37 + 33555283 = 33555320
61 + 33555259 = 33555320
79 + 33555241 = 33555320
103 + 33555217 = 33555320
157 + 33555163 = 33555320
241 + 33555079 = 33555320

Showing the first eight; more decompositions exist.
