Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103666, here are decompositions:

23 + 103643 = 103666
47 + 103619 = 103666
53 + 103613 = 103666
83 + 103583 = 103666
89 + 103577 = 103666
113 + 103553 = 103666
137 + 103529 = 103666
257 + 103409 = 103666

Showing the first eight; more decompositions exist.
