Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705556, here are decompositions:

5 + 8705551 = 8705556
7 + 8705549 = 8705556
29 + 8705527 = 8705556
37 + 8705519 = 8705556
73 + 8705483 = 8705556
89 + 8705467 = 8705556
103 + 8705453 = 8705556
107 + 8705449 = 8705556

Showing the first eight; more decompositions exist.
