Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55328, here are decompositions:

37 + 55291 = 55328
79 + 55249 = 55328
109 + 55219 = 55328
127 + 55201 = 55328
157 + 55171 = 55328
181 + 55147 = 55328
211 + 55117 = 55328
271 + 55057 = 55328

Showing the first eight; more decompositions exist.
