Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000806, here are decompositions:

13 + 1000793 = 1000806
29 + 1000777 = 1000806
43 + 1000763 = 1000806
83 + 1000723 = 1000806
109 + 1000697 = 1000806
127 + 1000679 = 1000806
137 + 1000669 = 1000806
139 + 1000667 = 1000806

Showing the first eight; more decompositions exist.
