Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002740, here are decompositions:

19 + 1002721 = 1002740
31 + 1002709 = 1002740
61 + 1002679 = 1002740
157 + 1002583 = 1002740
163 + 1002577 = 1002740
223 + 1002517 = 1002740
229 + 1002511 = 1002740
283 + 1002457 = 1002740

Showing the first eight; more decompositions exist.
