Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002580, here are decompositions:

3 + 1002577 = 1002580
11 + 1002569 = 1002580
53 + 1002527 = 1002580
113 + 1002467 = 1002580
233 + 1002347 = 1002580
239 + 1002341 = 1002580
281 + 1002299 = 1002580
317 + 1002263 = 1002580

Showing the first eight; more decompositions exist.
