Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607980, here are decompositions:

37 + 8607943 = 8607980
67 + 8607913 = 8607980
79 + 8607901 = 8607980
97 + 8607883 = 8607980
109 + 8607871 = 8607980
211 + 8607769 = 8607980
307 + 8607673 = 8607980
313 + 8607667 = 8607980

Showing the first eight; more decompositions exist.
