Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555490, here are decompositions:

3 + 555487 = 555490
29 + 555461 = 555490
71 + 555419 = 555490
107 + 555383 = 555490
197 + 555293 = 555490
233 + 555257 = 555490
239 + 555251 = 555490
269 + 555221 = 555490

Showing the first eight; more decompositions exist.
