Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556526, here are decompositions:

7 + 556519 = 556526
13 + 556513 = 556526
43 + 556483 = 556526
67 + 556459 = 556526
127 + 556399 = 556526
199 + 556327 = 556526
283 + 556243 = 556526
307 + 556219 = 556526

Showing the first eight; more decompositions exist.
