Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555278, here are decompositions:

181 + 555097 = 555278
379 + 554899 = 555278
439 + 554839 = 555278
457 + 554821 = 555278
487 + 554791 = 555278
499 + 554779 = 555278
547 + 554731 = 555278
571 + 554707 = 555278

Showing the first eight; more decompositions exist.
