Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670822, here are decompositions:

11 + 8670811 = 8670822
31 + 8670791 = 8670822
71 + 8670751 = 8670822
79 + 8670743 = 8670822
109 + 8670713 = 8670822
113 + 8670709 = 8670822
211 + 8670611 = 8670822
233 + 8670589 = 8670822

Showing the first eight; more decompositions exist.
