Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101856, here are decompositions:

17 + 101839 = 101856
19 + 101837 = 101856
23 + 101833 = 101856
59 + 101797 = 101856
67 + 101789 = 101856
107 + 101749 = 101856
109 + 101747 = 101856
137 + 101719 = 101856

Showing the first eight; more decompositions exist.
