Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103688, here are decompositions:

7 + 103681 = 103688
19 + 103669 = 103688
31 + 103657 = 103688
37 + 103651 = 103688
97 + 103591 = 103688
127 + 103561 = 103688
139 + 103549 = 103688
331 + 103357 = 103688

Showing the first eight; more decompositions exist.
