Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555522, here are decompositions:

31 + 555491 = 555522
61 + 555461 = 555522
83 + 555439 = 555522
101 + 555421 = 555522
103 + 555419 = 555522
131 + 555391 = 555522
139 + 555383 = 555522
173 + 555349 = 555522

Showing the first eight; more decompositions exist.
