Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501840, here are decompositions:

41 + 33501799 = 33501840
61 + 33501779 = 33501840
89 + 33501751 = 33501840
103 + 33501737 = 33501840
107 + 33501733 = 33501840
131 + 33501709 = 33501840
149 + 33501691 = 33501840
167 + 33501673 = 33501840

Showing the first eight; more decompositions exist.
