Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709760, here are decompositions:

23 + 8709737 = 8709760
29 + 8709731 = 8709760
41 + 8709719 = 8709760
47 + 8709713 = 8709760
83 + 8709677 = 8709760
107 + 8709653 = 8709760
113 + 8709647 = 8709760
149 + 8709611 = 8709760

Showing the first eight; more decompositions exist.
