Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123558, here are decompositions:

5 + 123553 = 123558
7 + 123551 = 123558
11 + 123547 = 123558
31 + 123527 = 123558
41 + 123517 = 123558
59 + 123499 = 123558
67 + 123491 = 123558
79 + 123479 = 123558

Showing the first eight; more decompositions exist.
