Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102556, here are decompositions:

5 + 102551 = 102556
17 + 102539 = 102556
23 + 102533 = 102556
53 + 102503 = 102556
59 + 102497 = 102556
149 + 102407 = 102556
197 + 102359 = 102556
227 + 102329 = 102556

Showing the first eight; more decompositions exist.
