Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607842, here are decompositions:

73 + 8607769 = 8607842
109 + 8607733 = 8607842
211 + 8607631 = 8607842
241 + 8607601 = 8607842
379 + 8607463 = 8607842
409 + 8607433 = 8607842
433 + 8607409 = 8607842
499 + 8607343 = 8607842

Showing the first eight; more decompositions exist.
