Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643170, here are decompositions:

37 + 8643133 = 8643170
61 + 8643109 = 8643170
79 + 8643091 = 8643170
157 + 8643013 = 8643170
181 + 8642989 = 8643170
223 + 8642947 = 8643170
307 + 8642863 = 8643170
313 + 8642857 = 8643170

Showing the first eight; more decompositions exist.
