Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556658, here are decompositions:

7 + 556651 = 556658
19 + 556639 = 556658
31 + 556627 = 556658
79 + 556579 = 556658
139 + 556519 = 556658
181 + 556477 = 556658
199 + 556459 = 556658
307 + 556351 = 556658

Showing the first eight; more decompositions exist.
