Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55518, here are decompositions:

7 + 55511 = 55518
17 + 55501 = 55518
31 + 55487 = 55518
61 + 55457 = 55518
79 + 55439 = 55518
107 + 55411 = 55518
137 + 55381 = 55518
167 + 55351 = 55518

Showing the first eight; more decompositions exist.
