Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647836, here are decompositions:

13 + 8647823 = 8647836
17 + 8647819 = 8647836
19 + 8647817 = 8647836
53 + 8647783 = 8647836
83 + 8647753 = 8647836
97 + 8647739 = 8647836
137 + 8647699 = 8647836
139 + 8647697 = 8647836

Showing the first eight; more decompositions exist.
