Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618820, here are decompositions:

3 + 33618817 = 33618820
41 + 33618779 = 33618820
47 + 33618773 = 33618820
71 + 33618749 = 33618820
83 + 33618737 = 33618820
101 + 33618719 = 33618820
149 + 33618671 = 33618820
461 + 33618359 = 33618820

Showing the first eight; more decompositions exist.
