Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648724, here are decompositions:

23 + 8648701 = 8648724
37 + 8648687 = 8648724
47 + 8648677 = 8648724
167 + 8648557 = 8648724
173 + 8648551 = 8648724
181 + 8648543 = 8648724
191 + 8648533 = 8648724
193 + 8648531 = 8648724

Showing the first eight; more decompositions exist.
