Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55556, here are decompositions:

157 + 55399 = 55556
223 + 55333 = 55556
307 + 55249 = 55556
313 + 55243 = 55556
337 + 55219 = 55556
349 + 55207 = 55556
409 + 55147 = 55556
439 + 55117 = 55556

Showing the first eight; more decompositions exist.
