Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648746, here are decompositions:

5 + 8648741 = 8648746
17 + 8648729 = 8648746
59 + 8648687 = 8648746
233 + 8648513 = 8648746
479 + 8648267 = 8648746
647 + 8648099 = 8648746
653 + 8648093 = 8648746
797 + 8647949 = 8648746

Showing the first eight; more decompositions exist.
