Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684860, here are decompositions:

29 + 8684831 = 8684860
71 + 8684789 = 8684860
89 + 8684771 = 8684860
101 + 8684759 = 8684860
113 + 8684747 = 8684860
167 + 8684693 = 8684860
263 + 8684597 = 8684860
347 + 8684513 = 8684860

Showing the first eight; more decompositions exist.
