Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678890, here are decompositions:

107 + 8678783 = 8678890
113 + 8678777 = 8678890
131 + 8678759 = 8678890
137 + 8678753 = 8678890
149 + 8678741 = 8678890
191 + 8678699 = 8678890
197 + 8678693 = 8678890
251 + 8678639 = 8678890

Showing the first eight; more decompositions exist.
