Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643090, here are decompositions:

7 + 8643083 = 8643090
13 + 8643077 = 8643090
31 + 8643059 = 8643090
37 + 8643053 = 8643090
67 + 8643023 = 8643090
101 + 8642989 = 8643090
139 + 8642951 = 8643090
151 + 8642939 = 8643090

Showing the first eight; more decompositions exist.
