Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581568, here are decompositions:

47 + 33581521 = 33581568
127 + 33581441 = 33581568
131 + 33581437 = 33581568
157 + 33581411 = 33581568
239 + 33581329 = 33581568
269 + 33581299 = 33581568
271 + 33581297 = 33581568
277 + 33581291 = 33581568

Showing the first eight; more decompositions exist.
