Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103728, here are decompositions:

5 + 103723 = 103728
29 + 103699 = 103728
41 + 103687 = 103728
47 + 103681 = 103728
59 + 103669 = 103728
71 + 103657 = 103728
109 + 103619 = 103728
137 + 103591 = 103728

Showing the first eight; more decompositions exist.
