Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709398, here are decompositions:

37 + 8709361 = 8709398
97 + 8709301 = 8709398
109 + 8709289 = 8709398
127 + 8709271 = 8709398
211 + 8709187 = 8709398
277 + 8709121 = 8709398
331 + 8709067 = 8709398
487 + 8708911 = 8709398

Showing the first eight; more decompositions exist.
