Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55516, here are decompositions:

5 + 55511 = 55516
29 + 55487 = 55516
47 + 55469 = 55516
59 + 55457 = 55516
173 + 55343 = 55516
179 + 55337 = 55516
257 + 55259 = 55516
353 + 55163 = 55516

Showing the first eight; more decompositions exist.
