Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556720, here are decompositions:

47 + 33556673 = 33556720
107 + 33556613 = 33556720
149 + 33556571 = 33556720
173 + 33556547 = 33556720
191 + 33556529 = 33556720
227 + 33556493 = 33556720
317 + 33556403 = 33556720
359 + 33556361 = 33556720

Showing the first eight; more decompositions exist.
