Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56158, here are decompositions:

59 + 56099 = 56158
71 + 56087 = 56158
149 + 56009 = 56158
191 + 55967 = 56158
227 + 55931 = 56158
257 + 55901 = 56158
269 + 55889 = 56158
359 + 55799 = 56158

Showing the first eight; more decompositions exist.
