Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121350, here are decompositions:

7 + 121343 = 121350
17 + 121333 = 121350
23 + 121327 = 121350
29 + 121321 = 121350
37 + 121313 = 121350
41 + 121309 = 121350
59 + 121291 = 121350
67 + 121283 = 121350

Showing the first eight; more decompositions exist.
