Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555380, here are decompositions:

3 + 33555377 = 33555380
7 + 33555373 = 33555380
97 + 33555283 = 33555380
109 + 33555271 = 33555380
139 + 33555241 = 33555380
163 + 33555217 = 33555380
181 + 33555199 = 33555380
307 + 33555073 = 33555380

Showing the first eight; more decompositions exist.
