Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103660, here are decompositions:

3 + 103657 = 103660
17 + 103643 = 103660
41 + 103619 = 103660
47 + 103613 = 103660
83 + 103577 = 103660
107 + 103553 = 103660
131 + 103529 = 103660
149 + 103511 = 103660

Showing the first eight; more decompositions exist.
