Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501780, here are decompositions:

29 + 33501751 = 33501780
43 + 33501737 = 33501780
47 + 33501733 = 33501780
61 + 33501719 = 33501780
71 + 33501709 = 33501780
73 + 33501707 = 33501780
83 + 33501697 = 33501780
89 + 33501691 = 33501780

Showing the first eight; more decompositions exist.
