Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102628, here are decompositions:

17 + 102611 = 102628
41 + 102587 = 102628
89 + 102539 = 102628
131 + 102497 = 102628
167 + 102461 = 102628
191 + 102437 = 102628
269 + 102359 = 102628
311 + 102317 = 102628

Showing the first eight; more decompositions exist.
