Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521870, here are decompositions:

7 + 33521863 = 33521870
43 + 33521827 = 33521870
73 + 33521797 = 33521870
139 + 33521731 = 33521870
157 + 33521713 = 33521870
181 + 33521689 = 33521870
223 + 33521647 = 33521870
241 + 33521629 = 33521870

Showing the first eight; more decompositions exist.
