Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644170, here are decompositions:

13 + 8644157 = 8644170
23 + 8644147 = 8644170
47 + 8644123 = 8644170
79 + 8644091 = 8644170
89 + 8644081 = 8644170
109 + 8644061 = 8644170
113 + 8644057 = 8644170
151 + 8644019 = 8644170

Showing the first eight; more decompositions exist.
