Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555398, here are decompositions:

7 + 555391 = 555398
37 + 555361 = 555398
61 + 555337 = 555398
97 + 555301 = 555398
307 + 555091 = 555398
421 + 554977 = 555398
439 + 554959 = 555398
499 + 554899 = 555398

Showing the first eight; more decompositions exist.
