Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558148, here are decompositions:

131 + 558017 = 558148
167 + 557981 = 558148
257 + 557891 = 558148
317 + 557831 = 558148
347 + 557801 = 558148
359 + 557789 = 558148
389 + 557759 = 558148
401 + 557747 = 558148

Showing the first eight; more decompositions exist.
