Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555640, here are decompositions:

3 + 555637 = 555640
47 + 555593 = 555640
83 + 555557 = 555640
149 + 555491 = 555640
179 + 555461 = 555640
257 + 555383 = 555640
347 + 555293 = 555640
353 + 555287 = 555640

Showing the first eight; more decompositions exist.
