Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55422, here are decompositions:

11 + 55411 = 55422
23 + 55399 = 55422
41 + 55381 = 55422
71 + 55351 = 55422
79 + 55343 = 55422
83 + 55339 = 55422
89 + 55333 = 55422
109 + 55313 = 55422

Showing the first eight; more decompositions exist.
