Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557866, here are decompositions:

29 + 33557837 = 33557866
59 + 33557807 = 33557866
113 + 33557753 = 33557866
137 + 33557729 = 33557866
239 + 33557627 = 33557866
263 + 33557603 = 33557866
269 + 33557597 = 33557866
443 + 33557423 = 33557866

Showing the first eight; more decompositions exist.
