Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555400, here are decompositions:

17 + 555383 = 555400
107 + 555293 = 555400
113 + 555287 = 555400
149 + 555251 = 555400
179 + 555221 = 555400
191 + 555209 = 555400
233 + 555167 = 555400
257 + 555143 = 555400

Showing the first eight; more decompositions exist.
