Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528780, here are decompositions:

11 + 33528769 = 33528780
13 + 33528767 = 33528780
29 + 33528751 = 33528780
41 + 33528739 = 33528780
59 + 33528721 = 33528780
73 + 33528707 = 33528780
101 + 33528679 = 33528780
127 + 33528653 = 33528780

Showing the first eight; more decompositions exist.
