Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474640, here are decompositions:

71 + 33474569 = 33474640
131 + 33474509 = 33474640
179 + 33474461 = 33474640
239 + 33474401 = 33474640
257 + 33474383 = 33474640
359 + 33474281 = 33474640
443 + 33474197 = 33474640
461 + 33474179 = 33474640

Showing the first eight; more decompositions exist.
