Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501778, here are decompositions:

41 + 33501737 = 33501778
59 + 33501719 = 33501778
71 + 33501707 = 33501778
197 + 33501581 = 33501778
491 + 33501287 = 33501778
509 + 33501269 = 33501778
587 + 33501191 = 33501778
701 + 33501077 = 33501778

Showing the first eight; more decompositions exist.
