Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121494, here are decompositions:

7 + 121487 = 121494
41 + 121453 = 121494
47 + 121447 = 121494
53 + 121441 = 121494
73 + 121421 = 121494
127 + 121367 = 121494
137 + 121357 = 121494
151 + 121343 = 121494

Showing the first eight; more decompositions exist.
