Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648562, here are decompositions:

5 + 8648557 = 8648562
11 + 8648551 = 8648562
19 + 8648543 = 8648562
29 + 8648533 = 8648562
31 + 8648531 = 8648562
61 + 8648501 = 8648562
103 + 8648459 = 8648562
149 + 8648413 = 8648562

Showing the first eight; more decompositions exist.
