Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556280, here are decompositions:

73 + 33556207 = 33556280
97 + 33556183 = 33556280
157 + 33556123 = 33556280
193 + 33556087 = 33556280
211 + 33556069 = 33556280
229 + 33556051 = 33556280
271 + 33556009 = 33556280
283 + 33555997 = 33556280

Showing the first eight; more decompositions exist.
