Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555520, here are decompositions:

29 + 555491 = 555520
59 + 555461 = 555520
101 + 555419 = 555520
137 + 555383 = 555520
227 + 555293 = 555520
233 + 555287 = 555520
263 + 555257 = 555520
269 + 555251 = 555520

Showing the first eight; more decompositions exist.
