Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555266, here are decompositions:

13 + 555253 = 555266
157 + 555109 = 555266
193 + 555073 = 555266
223 + 555043 = 555266
307 + 554959 = 555266
367 + 554899 = 555266
373 + 554893 = 555266
379 + 554887 = 555266

Showing the first eight; more decompositions exist.
