Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648860, here are decompositions:

23 + 8648837 = 8648860
29 + 8648831 = 8648860
47 + 8648813 = 8648860
113 + 8648747 = 8648860
131 + 8648729 = 8648860
173 + 8648687 = 8648860
317 + 8648543 = 8648860
347 + 8648513 = 8648860

Showing the first eight; more decompositions exist.
