Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558506, here are decompositions:

7 + 558499 = 558506
37 + 558469 = 558506
79 + 558427 = 558506
163 + 558343 = 558506
199 + 558307 = 558506
283 + 558223 = 558506
367 + 558139 = 558506
397 + 558109 = 558506

Showing the first eight; more decompositions exist.
