Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697824, here are decompositions:

13 + 8697811 = 8697824
127 + 8697697 = 8697824
211 + 8697613 = 8697824
313 + 8697511 = 8697824
523 + 8697301 = 8697824
547 + 8697277 = 8697824
571 + 8697253 = 8697824
661 + 8697163 = 8697824

Showing the first eight; more decompositions exist.
