Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55380, here are decompositions:

7 + 55373 = 55380
29 + 55351 = 55380
37 + 55343 = 55380
41 + 55339 = 55380
43 + 55337 = 55380
47 + 55333 = 55380
67 + 55313 = 55380
89 + 55291 = 55380

Showing the first eight; more decompositions exist.
