Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648574, here are decompositions:

17 + 8648557 = 8648574
23 + 8648551 = 8648574
31 + 8648543 = 8648574
37 + 8648537 = 8648574
41 + 8648533 = 8648574
43 + 8648531 = 8648574
61 + 8648513 = 8648574
73 + 8648501 = 8648574

Showing the first eight; more decompositions exist.
