Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55540, here are decompositions:

11 + 55529 = 55540
29 + 55511 = 55540
53 + 55487 = 55540
71 + 55469 = 55540
83 + 55457 = 55540
101 + 55439 = 55540
167 + 55373 = 55540
197 + 55343 = 55540

Showing the first eight; more decompositions exist.
