Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643010, here are decompositions:

59 + 8642951 = 8643010
71 + 8642939 = 8643010
83 + 8642927 = 8643010
107 + 8642903 = 8643010
113 + 8642897 = 8643010
149 + 8642861 = 8643010
191 + 8642819 = 8643010
263 + 8642747 = 8643010

Showing the first eight; more decompositions exist.
