Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55418, here are decompositions:

7 + 55411 = 55418
19 + 55399 = 55418
37 + 55381 = 55418
67 + 55351 = 55418
79 + 55339 = 55418
127 + 55291 = 55418
199 + 55219 = 55418
211 + 55207 = 55418

Showing the first eight; more decompositions exist.
