Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521670, here are decompositions:

23 + 33521647 = 33521670
41 + 33521629 = 33521670
47 + 33521623 = 33521670
131 + 33521539 = 33521670
139 + 33521531 = 33521670
199 + 33521471 = 33521670
233 + 33521437 = 33521670
239 + 33521431 = 33521670

Showing the first eight; more decompositions exist.
