Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521490, here are decompositions:

7 + 33521483 = 33521490
19 + 33521471 = 33521490
29 + 33521461 = 33521490
53 + 33521437 = 33521490
59 + 33521431 = 33521490
73 + 33521417 = 33521490
89 + 33521401 = 33521490
97 + 33521393 = 33521490

Showing the first eight; more decompositions exist.
