Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103686, here are decompositions:

5 + 103681 = 103686
17 + 103669 = 103686
29 + 103657 = 103686
43 + 103643 = 103686
67 + 103619 = 103686
73 + 103613 = 103686
103 + 103583 = 103686
109 + 103577 = 103686

Showing the first eight; more decompositions exist.
