Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10386, here are decompositions:

17 + 10369 = 10386
29 + 10357 = 10386
43 + 10343 = 10386
53 + 10333 = 10386
73 + 10313 = 10386
83 + 10303 = 10386
97 + 10289 = 10386
113 + 10273 = 10386

Showing the first eight; more decompositions exist.
