Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558172, here are decompositions:

5 + 558167 = 558172
23 + 558149 = 558172
59 + 558113 = 558172
89 + 558083 = 558172
191 + 557981 = 558172
269 + 557903 = 558172
281 + 557891 = 558172
311 + 557861 = 558172

Showing the first eight; more decompositions exist.
