Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102658, here are decompositions:

5 + 102653 = 102658
11 + 102647 = 102658
47 + 102611 = 102658
71 + 102587 = 102658
107 + 102551 = 102658
197 + 102461 = 102658
251 + 102407 = 102658
359 + 102299 = 102658

Showing the first eight; more decompositions exist.
