Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731740, here are decompositions:

19 + 8731721 = 8731740
29 + 8731711 = 8731740
41 + 8731699 = 8731740
53 + 8731687 = 8731740
67 + 8731673 = 8731740
79 + 8731661 = 8731740
97 + 8731643 = 8731740
103 + 8731637 = 8731740

Showing the first eight; more decompositions exist.
