Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101806, here are decompositions:

17 + 101789 = 101806
59 + 101747 = 101806
83 + 101723 = 101806
113 + 101693 = 101806
179 + 101627 = 101806
233 + 101573 = 101806
269 + 101537 = 101806
293 + 101513 = 101806

Showing the first eight; more decompositions exist.
