Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555880, here are decompositions:

179 + 33555701 = 33555880
233 + 33555647 = 33555880
251 + 33555629 = 33555880
263 + 33555617 = 33555880
269 + 33555611 = 33555880
317 + 33555563 = 33555880
353 + 33555527 = 33555880
383 + 33555497 = 33555880

Showing the first eight; more decompositions exist.
