Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558090, here are decompositions:

7 + 558083 = 558090
23 + 558067 = 558090
37 + 558053 = 558090
61 + 558029 = 558090
73 + 558017 = 558090
83 + 558007 = 558090
103 + 557987 = 558090
109 + 557981 = 558090

Showing the first eight; more decompositions exist.
