Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655100, here are decompositions:

29 + 8655071 = 8655100
53 + 8655047 = 8655100
59 + 8655041 = 8655100
71 + 8655029 = 8655100
89 + 8655011 = 8655100
227 + 8654873 = 8655100
263 + 8654837 = 8655100
347 + 8654753 = 8655100

Showing the first eight; more decompositions exist.
