Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104688, here are decompositions:

5 + 104683 = 104688
7 + 104681 = 104688
11 + 104677 = 104688
29 + 104659 = 104688
37 + 104651 = 104688
109 + 104579 = 104688
127 + 104561 = 104688
137 + 104551 = 104688

Showing the first eight; more decompositions exist.
