Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55524, here are decompositions:

13 + 55511 = 55524
23 + 55501 = 55524
37 + 55487 = 55524
67 + 55457 = 55524
83 + 55441 = 55524
113 + 55411 = 55524
151 + 55373 = 55524
173 + 55351 = 55524

Showing the first eight; more decompositions exist.
