Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556500, here are decompositions:

13 + 556487 = 556500
17 + 556483 = 556500
23 + 556477 = 556500
41 + 556459 = 556500
59 + 556441 = 556500
97 + 556403 = 556500
101 + 556399 = 556500
127 + 556373 = 556500

Showing the first eight; more decompositions exist.
