Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505778, here are decompositions:

157 + 33505621 = 33505778
199 + 33505579 = 33505778
211 + 33505567 = 33505778
331 + 33505447 = 33505778
337 + 33505441 = 33505778
601 + 33505177 = 33505778
661 + 33505117 = 33505778
727 + 33505051 = 33505778

Showing the first eight; more decompositions exist.
