Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012842, here are decompositions:

11 + 1012831 = 1012842
13 + 1012829 = 1012842
31 + 1012811 = 1012842
53 + 1012789 = 1012842
71 + 1012771 = 1012842
73 + 1012769 = 1012842
79 + 1012763 = 1012842
109 + 1012733 = 1012842

Showing the first eight; more decompositions exist.
