Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101686, here are decompositions:

5 + 101681 = 101686
23 + 101663 = 101686
59 + 101627 = 101686
83 + 101603 = 101686
113 + 101573 = 101686
149 + 101537 = 101686
173 + 101513 = 101686
197 + 101489 = 101686

Showing the first eight; more decompositions exist.
