Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555288, here are decompositions:

11 + 555277 = 555288
31 + 555257 = 555288
37 + 555251 = 555288
67 + 555221 = 555288
79 + 555209 = 555288
179 + 555109 = 555288
191 + 555097 = 555288
197 + 555091 = 555288

Showing the first eight; more decompositions exist.
