Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648140, here are decompositions:

29 + 8648111 = 8648140
41 + 8648099 = 8648140
47 + 8648093 = 8648140
107 + 8648033 = 8648140
173 + 8647967 = 8648140
191 + 8647949 = 8648140
227 + 8647913 = 8648140
251 + 8647889 = 8648140

Showing the first eight; more decompositions exist.
