Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555530, here are decompositions:

7 + 555523 = 555530
43 + 555487 = 555530
109 + 555421 = 555530
139 + 555391 = 555530
181 + 555349 = 555530
193 + 555337 = 555530
223 + 555307 = 555530
229 + 555301 = 555530

Showing the first eight; more decompositions exist.
