Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557860, here are decompositions:

23 + 33557837 = 33557860
53 + 33557807 = 33557860
71 + 33557789 = 33557860
107 + 33557753 = 33557860
131 + 33557729 = 33557860
179 + 33557681 = 33557860
197 + 33557663 = 33557860
233 + 33557627 = 33557860

Showing the first eight; more decompositions exist.
