Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555542, here are decompositions:

19 + 555523 = 555542
103 + 555439 = 555542
151 + 555391 = 555542
181 + 555361 = 555542
193 + 555349 = 555542
241 + 555301 = 555542
433 + 555109 = 555542
499 + 555043 = 555542

Showing the first eight; more decompositions exist.
