Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101876, here are decompositions:

3 + 101873 = 101876
7 + 101869 = 101876
13 + 101863 = 101876
37 + 101839 = 101876
43 + 101833 = 101876
79 + 101797 = 101876
127 + 101749 = 101876
139 + 101737 = 101876

Showing the first eight; more decompositions exist.
