Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102666, here are decompositions:

13 + 102653 = 102666
19 + 102647 = 102666
23 + 102643 = 102666
59 + 102607 = 102666
73 + 102593 = 102666
79 + 102587 = 102666
103 + 102563 = 102666
107 + 102559 = 102666

Showing the first eight; more decompositions exist.
