Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645100, here are decompositions:

19 + 8645081 = 8645100
29 + 8645071 = 8645100
47 + 8645053 = 8645100
53 + 8645047 = 8645100
71 + 8645029 = 8645100
89 + 8645011 = 8645100
109 + 8644991 = 8645100
137 + 8644963 = 8645100

Showing the first eight; more decompositions exist.
