Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55440, here are decompositions:

29 + 55411 = 55440
41 + 55399 = 55440
59 + 55381 = 55440
67 + 55373 = 55440
89 + 55351 = 55440
97 + 55343 = 55440
101 + 55339 = 55440
103 + 55337 = 55440

Showing the first eight; more decompositions exist.
