Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706564, here are decompositions:

7 + 8706557 = 8706564
11 + 8706553 = 8706564
17 + 8706547 = 8706564
37 + 8706527 = 8706564
67 + 8706497 = 8706564
101 + 8706463 = 8706564
103 + 8706461 = 8706564
107 + 8706457 = 8706564

Showing the first eight; more decompositions exist.
