Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102636, here are decompositions:

29 + 102607 = 102636
43 + 102593 = 102636
73 + 102563 = 102636
89 + 102547 = 102636
97 + 102539 = 102636
103 + 102533 = 102636
113 + 102523 = 102636
137 + 102499 = 102636

Showing the first eight; more decompositions exist.
