Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558458, here are decompositions:

31 + 558427 = 558458
37 + 558421 = 558458
139 + 558319 = 558458
151 + 558307 = 558458
337 + 558121 = 558458
349 + 558109 = 558458
367 + 558091 = 558458
601 + 557857 = 558458

Showing the first eight; more decompositions exist.
