Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101868, here are decompositions:

5 + 101863 = 101868
29 + 101839 = 101868
31 + 101837 = 101868
61 + 101807 = 101868
71 + 101797 = 101868
79 + 101789 = 101868
97 + 101771 = 101868
127 + 101741 = 101868

Showing the first eight; more decompositions exist.
