Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031842, here are decompositions:

5 + 1031837 = 1031842
11 + 1031831 = 1031842
29 + 1031813 = 1031842
83 + 1031759 = 1031842
89 + 1031753 = 1031842
101 + 1031741 = 1031842
113 + 1031729 = 1031842
173 + 1031669 = 1031842

Showing the first eight; more decompositions exist.
