Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043842, here are decompositions:

3 + 1043839 = 1043842
5 + 1043837 = 1043842
11 + 1043831 = 1043842
83 + 1043759 = 1043842
89 + 1043753 = 1043842
179 + 1043663 = 1043842
251 + 1043591 = 1043842
311 + 1043531 = 1043842

Showing the first eight; more decompositions exist.
