Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556566, here are decompositions:

7 + 33556559 = 33556566
19 + 33556547 = 33556566
37 + 33556529 = 33556566
59 + 33556507 = 33556566
67 + 33556499 = 33556566
73 + 33556493 = 33556566
83 + 33556483 = 33556566
107 + 33556459 = 33556566

Showing the first eight; more decompositions exist.
