Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557830, here are decompositions:

3 + 33557827 = 33557830
23 + 33557807 = 33557830
41 + 33557789 = 33557830
101 + 33557729 = 33557830
149 + 33557681 = 33557830
167 + 33557663 = 33557830
227 + 33557603 = 33557830
233 + 33557597 = 33557830

Showing the first eight; more decompositions exist.
