Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555870, here are decompositions:

11 + 33555859 = 33555870
17 + 33555853 = 33555870
53 + 33555817 = 33555870
71 + 33555799 = 33555870
113 + 33555757 = 33555870
167 + 33555703 = 33555870
191 + 33555679 = 33555870
211 + 33555659 = 33555870

Showing the first eight; more decompositions exist.
