Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705530, here are decompositions:

3 + 8705527 = 8705530
11 + 8705519 = 8705530
23 + 8705507 = 8705530
47 + 8705483 = 8705530
89 + 8705441 = 8705530
101 + 8705429 = 8705530
131 + 8705399 = 8705530
179 + 8705351 = 8705530

Showing the first eight; more decompositions exist.
