Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012830, here are decompositions:

19 + 1012811 = 1012830
41 + 1012789 = 1012830
59 + 1012771 = 1012830
61 + 1012769 = 1012830
67 + 1012763 = 1012830
79 + 1012751 = 1012830
97 + 1012733 = 1012830
109 + 1012721 = 1012830

Showing the first eight; more decompositions exist.
