Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647830, here are decompositions:

7 + 8647823 = 8647830
11 + 8647819 = 8647830
13 + 8647817 = 8647830
29 + 8647801 = 8647830
47 + 8647783 = 8647830
71 + 8647759 = 8647830
131 + 8647699 = 8647830
173 + 8647657 = 8647830

Showing the first eight; more decompositions exist.
