Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577640, here are decompositions:

3 + 33577637 = 33577640
67 + 33577573 = 33577640
127 + 33577513 = 33577640
139 + 33577501 = 33577640
181 + 33577459 = 33577640
211 + 33577429 = 33577640
433 + 33577207 = 33577640
457 + 33577183 = 33577640

Showing the first eight; more decompositions exist.
