Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645662, here are decompositions:

5 + 8645657 = 8645662
29 + 8645633 = 8645662
83 + 8645579 = 8645662
281 + 8645381 = 8645662
401 + 8645261 = 8645662
419 + 8645243 = 8645662
521 + 8645141 = 8645662
653 + 8645009 = 8645662

Showing the first eight; more decompositions exist.
