Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55480, here are decompositions:

11 + 55469 = 55480
23 + 55457 = 55480
41 + 55439 = 55480
107 + 55373 = 55480
137 + 55343 = 55480
149 + 55331 = 55480
167 + 55313 = 55480
251 + 55229 = 55480

Showing the first eight; more decompositions exist.
