Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587878, here are decompositions:

11 + 33587867 = 33587878
47 + 33587831 = 33587878
89 + 33587789 = 33587878
461 + 33587417 = 33587878
521 + 33587357 = 33587878
557 + 33587321 = 33587878
617 + 33587261 = 33587878
641 + 33587237 = 33587878

Showing the first eight; more decompositions exist.
