Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030842, here are decompositions:

11 + 1030831 = 1030842
19 + 1030823 = 1030842
31 + 1030811 = 1030842
41 + 1030801 = 1030842
79 + 1030763 = 1030842
83 + 1030759 = 1030842
101 + 1030741 = 1030842
103 + 1030739 = 1030842

Showing the first eight; more decompositions exist.
