Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121242, here are decompositions:

13 + 121229 = 121242
53 + 121189 = 121242
61 + 121181 = 121242
71 + 121171 = 121242
73 + 121169 = 121242
103 + 121139 = 121242
179 + 121063 = 121242
181 + 121061 = 121242

Showing the first eight; more decompositions exist.
