Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501820, here are decompositions:

29 + 33501791 = 33501820
41 + 33501779 = 33501820
83 + 33501737 = 33501820
101 + 33501719 = 33501820
113 + 33501707 = 33501820
167 + 33501653 = 33501820
239 + 33501581 = 33501820
347 + 33501473 = 33501820

Showing the first eight; more decompositions exist.
