Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521610, here are decompositions:

61 + 33521549 = 33521610
71 + 33521539 = 33521610
79 + 33521531 = 33521610
127 + 33521483 = 33521610
139 + 33521471 = 33521610
149 + 33521461 = 33521610
173 + 33521437 = 33521610
179 + 33521431 = 33521610

Showing the first eight; more decompositions exist.
