Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101816, here are decompositions:

19 + 101797 = 101816
67 + 101749 = 101816
79 + 101737 = 101816
97 + 101719 = 101816
163 + 101653 = 101816
283 + 101533 = 101816
313 + 101503 = 101816
349 + 101467 = 101816

Showing the first eight; more decompositions exist.
