Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605100, here are decompositions:

43 + 8605057 = 8605100
109 + 8604991 = 8605100
139 + 8604961 = 8605100
157 + 8604943 = 8605100
277 + 8604823 = 8605100
331 + 8604769 = 8605100
349 + 8604751 = 8605100
367 + 8604733 = 8605100

Showing the first eight; more decompositions exist.
