Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558128, here are decompositions:

7 + 558121 = 558128
19 + 558109 = 558128
37 + 558091 = 558128
61 + 558067 = 558128
229 + 557899 = 558128
271 + 557857 = 558128
349 + 557779 = 558128
367 + 557761 = 558128

Showing the first eight; more decompositions exist.
