Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557776, here are decompositions:

23 + 33557753 = 33557776
47 + 33557729 = 33557776
113 + 33557663 = 33557776
149 + 33557627 = 33557776
173 + 33557603 = 33557776
179 + 33557597 = 33557776
233 + 33557543 = 33557776
347 + 33557429 = 33557776

Showing the first eight; more decompositions exist.
