Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105246, here are decompositions:

7 + 105239 = 105246
17 + 105229 = 105246
19 + 105227 = 105246
47 + 105199 = 105246
73 + 105173 = 105246
79 + 105167 = 105246
103 + 105143 = 105246
109 + 105137 = 105246

Showing the first eight; more decompositions exist.
