Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521430, here are decompositions:

13 + 33521417 = 33521430
29 + 33521401 = 33521430
37 + 33521393 = 33521430
109 + 33521321 = 33521430
193 + 33521237 = 33521430
211 + 33521219 = 33521430
251 + 33521179 = 33521430
331 + 33521099 = 33521430

Showing the first eight; more decompositions exist.
