Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558138, here are decompositions:

17 + 558121 = 558138
29 + 558109 = 558138
47 + 558091 = 558138
71 + 558067 = 558138
109 + 558029 = 558138
131 + 558007 = 558138
151 + 557987 = 558138
157 + 557981 = 558138

Showing the first eight; more decompositions exist.
