Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556742, here are decompositions:

19 + 556723 = 556742
103 + 556639 = 556742
163 + 556579 = 556742
223 + 556519 = 556742
229 + 556513 = 556742
283 + 556459 = 556742
421 + 556321 = 556742
463 + 556279 = 556742

Showing the first eight; more decompositions exist.
