Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555538, here are decompositions:

17 + 555521 = 555538
47 + 555491 = 555538
251 + 555287 = 555538
281 + 555257 = 555538
317 + 555221 = 555538
419 + 555119 = 555538
461 + 555077 = 555538
509 + 555029 = 555538

Showing the first eight; more decompositions exist.
