Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558020, here are decompositions:

3 + 558017 = 558020
13 + 558007 = 558020
157 + 557863 = 558020
163 + 557857 = 558020
241 + 557779 = 558020
277 + 557743 = 558020
349 + 557671 = 558020
409 + 557611 = 558020

Showing the first eight; more decompositions exist.
