Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689570, here are decompositions:

17 + 8689553 = 8689570
41 + 8689529 = 8689570
89 + 8689481 = 8689570
107 + 8689463 = 8689570
137 + 8689433 = 8689570
251 + 8689319 = 8689570
269 + 8689301 = 8689570
311 + 8689259 = 8689570

Showing the first eight; more decompositions exist.
