Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509370, here are decompositions:

17 + 33509353 = 33509370
43 + 33509327 = 33509370
47 + 33509323 = 33509370
79 + 33509291 = 33509370
101 + 33509269 = 33509370
113 + 33509257 = 33509370
127 + 33509243 = 33509370
151 + 33509219 = 33509370

Showing the first eight; more decompositions exist.
