Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556542, here are decompositions:

5 + 556537 = 556542
23 + 556519 = 556542
29 + 556513 = 556542
59 + 556483 = 556542
83 + 556459 = 556542
101 + 556441 = 556542
139 + 556403 = 556542
191 + 556351 = 556542

Showing the first eight; more decompositions exist.
