Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709642, here are decompositions:

31 + 8709611 = 8709642
79 + 8709563 = 8709642
89 + 8709553 = 8709642
173 + 8709469 = 8709642
181 + 8709461 = 8709642
199 + 8709443 = 8709642
211 + 8709431 = 8709642
269 + 8709373 = 8709642

Showing the first eight; more decompositions exist.
