Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557678, here are decompositions:

61 + 33557617 = 33557678
157 + 33557521 = 33557678
211 + 33557467 = 33557678
337 + 33557341 = 33557678
421 + 33557257 = 33557678
547 + 33557131 = 33557678
577 + 33557101 = 33557678
601 + 33557077 = 33557678

Showing the first eight; more decompositions exist.
