Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643250, here are decompositions:

41 + 8643209 = 8643250
53 + 8643197 = 8643250
101 + 8643149 = 8643250
107 + 8643143 = 8643250
113 + 8643137 = 8643250
167 + 8643083 = 8643250
173 + 8643077 = 8643250
191 + 8643059 = 8643250

Showing the first eight; more decompositions exist.
