Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55400, here are decompositions:

19 + 55381 = 55400
61 + 55339 = 55400
67 + 55333 = 55400
109 + 55291 = 55400
151 + 55249 = 55400
157 + 55243 = 55400
181 + 55219 = 55400
193 + 55207 = 55400

Showing the first eight; more decompositions exist.
