Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642662, here are decompositions:

11 + 8642651 = 8642662
29 + 8642633 = 8642662
71 + 8642591 = 8642662
173 + 8642489 = 8642662
233 + 8642429 = 8642662
359 + 8642303 = 8642662
503 + 8642159 = 8642662
521 + 8642141 = 8642662

Showing the first eight; more decompositions exist.
