Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12458, here are decompositions:

7 + 12451 = 12458
37 + 12421 = 12458
67 + 12391 = 12458
79 + 12379 = 12458
157 + 12301 = 12458
181 + 12277 = 12458
349 + 12109 = 12458
409 + 12049 = 12458

Showing the first eight; more decompositions exist.
