Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558428, here are decompositions:

7 + 558421 = 558428
109 + 558319 = 558428
139 + 558289 = 558428
307 + 558121 = 558428
337 + 558091 = 558428
421 + 558007 = 558428
571 + 557857 = 558428
757 + 557671 = 558428

Showing the first eight; more decompositions exist.
