Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55486, here are decompositions:

17 + 55469 = 55486
29 + 55457 = 55486
47 + 55439 = 55486
113 + 55373 = 55486
149 + 55337 = 55486
173 + 55313 = 55486
227 + 55259 = 55486
257 + 55229 = 55486

Showing the first eight; more decompositions exist.
