Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102826, here are decompositions:

29 + 102797 = 102826
149 + 102677 = 102826
173 + 102653 = 102826
179 + 102647 = 102826
233 + 102593 = 102826
239 + 102587 = 102826
263 + 102563 = 102826
293 + 102533 = 102826

Showing the first eight; more decompositions exist.
