Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555318, here are decompositions:

11 + 555307 = 555318
17 + 555301 = 555318
31 + 555287 = 555318
41 + 555277 = 555318
61 + 555257 = 555318
67 + 555251 = 555318
97 + 555221 = 555318
109 + 555209 = 555318

Showing the first eight; more decompositions exist.
