Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040820, here are decompositions:

7 + 1040813 = 1040820
13 + 1040807 = 1040820
17 + 1040803 = 1040820
23 + 1040797 = 1040820
37 + 1040783 = 1040820
41 + 1040779 = 1040820
43 + 1040777 = 1040820
71 + 1040749 = 1040820

Showing the first eight; more decompositions exist.
