Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705490, here are decompositions:

7 + 8705483 = 8705490
23 + 8705467 = 8705490
29 + 8705461 = 8705490
37 + 8705453 = 8705490
41 + 8705449 = 8705490
47 + 8705443 = 8705490
61 + 8705429 = 8705490
71 + 8705419 = 8705490

Showing the first eight; more decompositions exist.
