Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521578, here are decompositions:

29 + 33521549 = 33521578
47 + 33521531 = 33521578
107 + 33521471 = 33521578
257 + 33521321 = 33521578
359 + 33521219 = 33521578
401 + 33521177 = 33521578
479 + 33521099 = 33521578
491 + 33521087 = 33521578

Showing the first eight; more decompositions exist.
