Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102508, here are decompositions:

5 + 102503 = 102508
11 + 102497 = 102508
47 + 102461 = 102508
71 + 102437 = 102508
101 + 102407 = 102508
149 + 102359 = 102508
179 + 102329 = 102508
191 + 102317 = 102508

Showing the first eight; more decompositions exist.
