Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33622640, here are decompositions:

19 + 33622621 = 33622640
151 + 33622489 = 33622640
199 + 33622441 = 33622640
211 + 33622429 = 33622640
223 + 33622417 = 33622640
229 + 33622411 = 33622640
241 + 33622399 = 33622640
277 + 33622363 = 33622640

Showing the first eight; more decompositions exist.
