Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10788, here are decompositions:

7 + 10781 = 10788
17 + 10771 = 10788
59 + 10729 = 10788
79 + 10709 = 10788
97 + 10691 = 10788
101 + 10687 = 10788
131 + 10657 = 10788
137 + 10651 = 10788

Showing the first eight; more decompositions exist.
