Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642516, here are decompositions:

7 + 8642509 = 8642516
67 + 8642449 = 8642516
397 + 8642119 = 8642516
409 + 8642107 = 8642516
439 + 8642077 = 8642516
457 + 8642059 = 8642516
607 + 8641909 = 8642516
643 + 8641873 = 8642516

Showing the first eight; more decompositions exist.
