Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55388, here are decompositions:

7 + 55381 = 55388
37 + 55351 = 55388
97 + 55291 = 55388
139 + 55249 = 55388
181 + 55207 = 55388
241 + 55147 = 55388
271 + 55117 = 55388
331 + 55057 = 55388

Showing the first eight; more decompositions exist.
