Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557892, here are decompositions:

13 + 33557879 = 33557892
83 + 33557809 = 33557892
103 + 33557789 = 33557892
139 + 33557753 = 33557892
163 + 33557729 = 33557892
191 + 33557701 = 33557892
211 + 33557681 = 33557892
229 + 33557663 = 33557892

Showing the first eight; more decompositions exist.
