Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635470, here are decompositions:

29 + 8635441 = 8635470
37 + 8635433 = 8635470
47 + 8635423 = 8635470
61 + 8635409 = 8635470
89 + 8635381 = 8635470
149 + 8635321 = 8635470
157 + 8635313 = 8635470
191 + 8635279 = 8635470

Showing the first eight; more decompositions exist.
