Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102798, here are decompositions:

5 + 102793 = 102798
29 + 102769 = 102798
37 + 102761 = 102798
97 + 102701 = 102798
131 + 102667 = 102798
151 + 102647 = 102798
191 + 102607 = 102798
211 + 102587 = 102798

Showing the first eight; more decompositions exist.
