Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557992, here are decompositions:

5 + 33557987 = 33557992
11 + 33557981 = 33557992
71 + 33557921 = 33557992
101 + 33557891 = 33557992
113 + 33557879 = 33557992
239 + 33557753 = 33557992
263 + 33557729 = 33557992
311 + 33557681 = 33557992

Showing the first eight; more decompositions exist.
