Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556580, here are decompositions:

73 + 33556507 = 33556580
97 + 33556483 = 33556580
151 + 33556429 = 33556580
157 + 33556423 = 33556580
181 + 33556399 = 33556580
199 + 33556381 = 33556580
223 + 33556357 = 33556580
241 + 33556339 = 33556580

Showing the first eight; more decompositions exist.
