Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002730, here are decompositions:

11 + 1002719 = 1002730
17 + 1002713 = 1002730
83 + 1002647 = 1002730
107 + 1002623 = 1002730
227 + 1002503 = 1002730
263 + 1002467 = 1002730
353 + 1002377 = 1002730
383 + 1002347 = 1002730

Showing the first eight; more decompositions exist.
