Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577878, here are decompositions:

7 + 33577871 = 33577878
31 + 33577847 = 33577878
97 + 33577781 = 33577878
151 + 33577727 = 33577878
157 + 33577721 = 33577878
227 + 33577651 = 33577878
241 + 33577637 = 33577878
307 + 33577571 = 33577878

Showing the first eight; more decompositions exist.
