Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642652, here are decompositions:

19 + 8642633 = 8642652
61 + 8642591 = 8642652
71 + 8642581 = 8642652
163 + 8642489 = 8642652
199 + 8642453 = 8642652
223 + 8642429 = 8642652
269 + 8642383 = 8642652
349 + 8642303 = 8642652

Showing the first eight; more decompositions exist.
