Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56558, here are decompositions:

31 + 56527 = 56558
79 + 56479 = 56558
127 + 56431 = 56558
157 + 56401 = 56558
181 + 56377 = 56558
199 + 56359 = 56558
349 + 56209 = 56558
379 + 56179 = 56558

Showing the first eight; more decompositions exist.
