Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644782, here are decompositions:

11 + 8644771 = 8644782
31 + 8644751 = 8644782
53 + 8644729 = 8644782
59 + 8644723 = 8644782
79 + 8644703 = 8644782
103 + 8644679 = 8644782
131 + 8644651 = 8644782
149 + 8644633 = 8644782

Showing the first eight; more decompositions exist.
