Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521518, here are decompositions:

47 + 33521471 = 33521518
101 + 33521417 = 33521518
197 + 33521321 = 33521518
281 + 33521237 = 33521518
347 + 33521171 = 33521518
419 + 33521099 = 33521518
431 + 33521087 = 33521518
461 + 33521057 = 33521518

Showing the first eight; more decompositions exist.
