Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671740, here are decompositions:

19 + 8671721 = 8671740
29 + 8671711 = 8671740
31 + 8671709 = 8671740
43 + 8671697 = 8671740
71 + 8671669 = 8671740
101 + 8671639 = 8671740
107 + 8671633 = 8671740
109 + 8671631 = 8671740

Showing the first eight; more decompositions exist.
