Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555320, here are decompositions:

13 + 555307 = 555320
19 + 555301 = 555320
43 + 555277 = 555320
67 + 555253 = 555320
211 + 555109 = 555320
223 + 555097 = 555320
229 + 555091 = 555320
277 + 555043 = 555320

Showing the first eight; more decompositions exist.
