Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555518, here are decompositions:

31 + 555487 = 555518
79 + 555439 = 555518
97 + 555421 = 555518
127 + 555391 = 555518
157 + 555361 = 555518
181 + 555337 = 555518
211 + 555307 = 555518
241 + 555277 = 555518

Showing the first eight; more decompositions exist.
