Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642068, here are decompositions:

5 + 8642063 = 8642068
11 + 8642057 = 8642068
41 + 8642027 = 8642068
251 + 8641817 = 8642068
359 + 8641709 = 8642068
521 + 8641547 = 8642068
599 + 8641469 = 8642068
647 + 8641421 = 8642068

Showing the first eight; more decompositions exist.
