Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556866, here are decompositions:

19 + 33556847 = 33556866
29 + 33556837 = 33556866
43 + 33556823 = 33556866
97 + 33556769 = 33556866
193 + 33556673 = 33556866
269 + 33556597 = 33556866
307 + 33556559 = 33556866
337 + 33556529 = 33556866

Showing the first eight; more decompositions exist.
