Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558166, here are decompositions:

17 + 558149 = 558166
53 + 558113 = 558166
83 + 558083 = 558166
113 + 558053 = 558166
137 + 558029 = 558166
149 + 558017 = 558166
179 + 557987 = 558166
239 + 557927 = 558166

Showing the first eight; more decompositions exist.
