Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557980, here are decompositions:

59 + 33557921 = 33557980
89 + 33557891 = 33557980
101 + 33557879 = 33557980
173 + 33557807 = 33557980
191 + 33557789 = 33557980
227 + 33557753 = 33557980
251 + 33557729 = 33557980
317 + 33557663 = 33557980

Showing the first eight; more decompositions exist.
