Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104558, here are decompositions:

7 + 104551 = 104558
31 + 104527 = 104558
67 + 104491 = 104558
79 + 104479 = 104558
211 + 104347 = 104558
271 + 104287 = 104558
277 + 104281 = 104558
379 + 104179 = 104558

Showing the first eight; more decompositions exist.
