Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101558, here are decompositions:

31 + 101527 = 101558
109 + 101449 = 101558
139 + 101419 = 101558
181 + 101377 = 101558
199 + 101359 = 101558
211 + 101347 = 101558
271 + 101287 = 101558
277 + 101281 = 101558

Showing the first eight; more decompositions exist.
