Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102506, here are decompositions:

3 + 102503 = 102506
7 + 102499 = 102506
73 + 102433 = 102506
97 + 102409 = 102506
109 + 102397 = 102506
139 + 102367 = 102506
277 + 102229 = 102506
307 + 102199 = 102506

Showing the first eight; more decompositions exist.
