Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5566, here are decompositions:

3 + 5563 = 5566
47 + 5519 = 5566
59 + 5507 = 5566
83 + 5483 = 5566
89 + 5477 = 5566
149 + 5417 = 5566
167 + 5399 = 5566
173 + 5393 = 5566

Showing the first eight; more decompositions exist.
