Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629470, here are decompositions:

23 + 8629447 = 8629470
29 + 8629441 = 8629470
37 + 8629433 = 8629470
41 + 8629429 = 8629470
61 + 8629409 = 8629470
127 + 8629343 = 8629470
137 + 8629333 = 8629470
173 + 8629297 = 8629470

Showing the first eight; more decompositions exist.
