Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557686, here are decompositions:

3 + 33557683 = 33557686
5 + 33557681 = 33557686
23 + 33557663 = 33557686
59 + 33557627 = 33557686
83 + 33557603 = 33557686
89 + 33557597 = 33557686
233 + 33557453 = 33557686
257 + 33557429 = 33557686

Showing the first eight; more decompositions exist.
