Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121470, here are decompositions:

17 + 121453 = 121470
23 + 121447 = 121470
29 + 121441 = 121470
31 + 121439 = 121470
67 + 121403 = 121470
101 + 121369 = 121470
103 + 121367 = 121470
113 + 121357 = 121470

Showing the first eight; more decompositions exist.
