Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55320, here are decompositions:

7 + 55313 = 55320
29 + 55291 = 55320
61 + 55259 = 55320
71 + 55249 = 55320
101 + 55219 = 55320
103 + 55217 = 55320
107 + 55213 = 55320
113 + 55207 = 55320

Showing the first eight; more decompositions exist.
