Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697740, here are decompositions:

43 + 8697697 = 8697740
127 + 8697613 = 8697740
229 + 8697511 = 8697740
241 + 8697499 = 8697740
307 + 8697433 = 8697740
397 + 8697343 = 8697740
439 + 8697301 = 8697740
463 + 8697277 = 8697740

Showing the first eight; more decompositions exist.
