Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101146, here are decompositions:

5 + 101141 = 101146
29 + 101117 = 101146
83 + 101063 = 101146
137 + 101009 = 101146
233 + 100913 = 101146
239 + 100907 = 101146
293 + 100853 = 101146
317 + 100829 = 101146

Showing the first eight; more decompositions exist.
