Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555206, here are decompositions:

97 + 555109 = 555206
109 + 555097 = 555206
163 + 555043 = 555206
229 + 554977 = 555206
283 + 554923 = 555206
307 + 554899 = 555206
313 + 554893 = 555206
367 + 554839 = 555206

Showing the first eight; more decompositions exist.
