Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002830, here are decompositions:

13 + 1002817 = 1002830
43 + 1002787 = 1002830
61 + 1002769 = 1002830
79 + 1002751 = 1002830
109 + 1002721 = 1002830
151 + 1002679 = 1002830
211 + 1002619 = 1002830
277 + 1002553 = 1002830

Showing the first eight; more decompositions exist.
