Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121146, here are decompositions:

7 + 121139 = 121146
23 + 121123 = 121146
79 + 121067 = 121146
83 + 121063 = 121146
107 + 121039 = 121146
127 + 121019 = 121146
139 + 121007 = 121146
149 + 120997 = 121146

Showing the first eight; more decompositions exist.
