Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491560, here are decompositions:

17 + 33491543 = 33491560
23 + 33491537 = 33491560
71 + 33491489 = 33491560
101 + 33491459 = 33491560
173 + 33491387 = 33491560
191 + 33491369 = 33491560
197 + 33491363 = 33491560
227 + 33491333 = 33491560

Showing the first eight; more decompositions exist.
