Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557886, here are decompositions:

7 + 33557879 = 33557886
59 + 33557827 = 33557886
79 + 33557807 = 33557886
97 + 33557789 = 33557886
137 + 33557749 = 33557886
149 + 33557737 = 33557886
157 + 33557729 = 33557886
179 + 33557707 = 33557886

Showing the first eight; more decompositions exist.
