Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10146, here are decompositions:

5 + 10141 = 10146
7 + 10139 = 10146
13 + 10133 = 10146
43 + 10103 = 10146
47 + 10099 = 10146
53 + 10093 = 10146
67 + 10079 = 10146
79 + 10067 = 10146

Showing the first eight; more decompositions exist.
