Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103788, here are decompositions:

19 + 103769 = 103788
89 + 103699 = 103788
101 + 103687 = 103788
107 + 103681 = 103788
131 + 103657 = 103788
137 + 103651 = 103788
197 + 103591 = 103788
211 + 103577 = 103788

Showing the first eight; more decompositions exist.
