Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1036840, here are decompositions:

11 + 1036829 = 1036840
41 + 1036799 = 1036840
47 + 1036793 = 1036840
53 + 1036787 = 1036840
71 + 1036769 = 1036840
83 + 1036757 = 1036840
89 + 1036751 = 1036840
173 + 1036667 = 1036840

Showing the first eight; more decompositions exist.
