Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605406, here are decompositions:

3 + 8605403 = 8605406
37 + 8605369 = 8605406
109 + 8605297 = 8605406
349 + 8605057 = 8605406
463 + 8604943 = 8605406
673 + 8604733 = 8605406
709 + 8604697 = 8605406
739 + 8604667 = 8605406

Showing the first eight; more decompositions exist.
