Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555438, here are decompositions:

17 + 555421 = 555438
19 + 555419 = 555438
47 + 555391 = 555438
89 + 555349 = 555438
101 + 555337 = 555438
131 + 555307 = 555438
137 + 555301 = 555438
151 + 555287 = 555438

Showing the first eight; more decompositions exist.
