Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007842, here are decompositions:

23 + 1007819 = 1007842
29 + 1007813 = 1007842
41 + 1007801 = 1007842
53 + 1007789 = 1007842
71 + 1007771 = 1007842
83 + 1007759 = 1007842
89 + 1007753 = 1007842
113 + 1007729 = 1007842

Showing the first eight; more decompositions exist.
