Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55558, here are decompositions:

11 + 55547 = 55558
17 + 55541 = 55558
29 + 55529 = 55558
47 + 55511 = 55558
71 + 55487 = 55558
89 + 55469 = 55558
101 + 55457 = 55558
227 + 55331 = 55558

Showing the first eight; more decompositions exist.
