Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640030, here are decompositions:

13 + 8640017 = 8640030
17 + 8640013 = 8640030
29 + 8640001 = 8640030
43 + 8639987 = 8640030
53 + 8639977 = 8640030
79 + 8639951 = 8640030
107 + 8639923 = 8640030
109 + 8639921 = 8640030

Showing the first eight; more decompositions exist.
