Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642684, here are decompositions:

103 + 8642581 = 8642684
151 + 8642533 = 8642684
487 + 8642197 = 8642684
577 + 8642107 = 8642684
607 + 8642077 = 8642684
727 + 8641957 = 8642684
811 + 8641873 = 8642684
877 + 8641807 = 8642684

Showing the first eight; more decompositions exist.
