Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591760, here are decompositions:

13 + 8591747 = 8591760
43 + 8591717 = 8591760
71 + 8591689 = 8591760
97 + 8591663 = 8591760
127 + 8591633 = 8591760
137 + 8591623 = 8591760
157 + 8591603 = 8591760
167 + 8591593 = 8591760

Showing the first eight; more decompositions exist.
