Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705470, here are decompositions:

3 + 8705467 = 8705470
17 + 8705453 = 8705470
29 + 8705441 = 8705470
41 + 8705429 = 8705470
71 + 8705399 = 8705470
101 + 8705369 = 8705470
173 + 8705297 = 8705470
233 + 8705237 = 8705470

Showing the first eight; more decompositions exist.
