Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477640, here are decompositions:

41 + 33477599 = 33477640
113 + 33477527 = 33477640
149 + 33477491 = 33477640
167 + 33477473 = 33477640
173 + 33477467 = 33477640
227 + 33477413 = 33477640
293 + 33477347 = 33477640
389 + 33477251 = 33477640

Showing the first eight; more decompositions exist.
