Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102862, here are decompositions:

3 + 102859 = 102862
101 + 102761 = 102862
251 + 102611 = 102862
269 + 102593 = 102862
311 + 102551 = 102862
359 + 102503 = 102862
401 + 102461 = 102862
503 + 102359 = 102862

Showing the first eight; more decompositions exist.
