Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557890, here are decompositions:

11 + 33557879 = 33557890
53 + 33557837 = 33557890
83 + 33557807 = 33557890
101 + 33557789 = 33557890
137 + 33557753 = 33557890
227 + 33557663 = 33557890
263 + 33557627 = 33557890
293 + 33557597 = 33557890

Showing the first eight; more decompositions exist.
