Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121458, here are decompositions:

5 + 121453 = 121458
11 + 121447 = 121458
17 + 121441 = 121458
19 + 121439 = 121458
37 + 121421 = 121458
79 + 121379 = 121458
89 + 121369 = 121458
101 + 121357 = 121458

Showing the first eight; more decompositions exist.
