Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55238, here are decompositions:

19 + 55219 = 55238
31 + 55207 = 55238
37 + 55201 = 55238
67 + 55171 = 55238
181 + 55057 = 55238
229 + 55009 = 55238
331 + 54907 = 55238
409 + 54829 = 55238

Showing the first eight; more decompositions exist.
