Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109686, here are decompositions:

13 + 109673 = 109686
23 + 109663 = 109686
47 + 109639 = 109686
67 + 109619 = 109686
89 + 109597 = 109686
97 + 109589 = 109686
103 + 109583 = 109686
107 + 109579 = 109686

Showing the first eight; more decompositions exist.
