Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643070, here are decompositions:

11 + 8643059 = 8643070
17 + 8643053 = 8643070
47 + 8643023 = 8643070
131 + 8642939 = 8643070
167 + 8642903 = 8643070
173 + 8642897 = 8643070
251 + 8642819 = 8643070
347 + 8642723 = 8643070

Showing the first eight; more decompositions exist.
