Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55600, here are decompositions:

11 + 55589 = 55600
53 + 55547 = 55600
59 + 55541 = 55600
71 + 55529 = 55600
89 + 55511 = 55600
113 + 55487 = 55600
131 + 55469 = 55600
227 + 55373 = 55600

Showing the first eight; more decompositions exist.
