Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501390, here are decompositions:

19 + 33501371 = 33501390
23 + 33501367 = 33501390
71 + 33501319 = 33501390
89 + 33501301 = 33501390
101 + 33501289 = 33501390
103 + 33501287 = 33501390
137 + 33501253 = 33501390
151 + 33501239 = 33501390

Showing the first eight; more decompositions exist.
