Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102146, here are decompositions:

7 + 102139 = 102146
43 + 102103 = 102146
67 + 102079 = 102146
103 + 102043 = 102146
127 + 102019 = 102146
229 + 101917 = 102146
277 + 101869 = 102146
283 + 101863 = 102146

Showing the first eight; more decompositions exist.
