Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521250, here are decompositions:

13 + 33521237 = 33521250
29 + 33521221 = 33521250
31 + 33521219 = 33521250
71 + 33521179 = 33521250
73 + 33521177 = 33521250
79 + 33521171 = 33521250
109 + 33521141 = 33521250
151 + 33521099 = 33521250

Showing the first eight; more decompositions exist.
