Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717690, here are decompositions:

13 + 8717677 = 8717690
67 + 8717623 = 8717690
127 + 8717563 = 8717690
139 + 8717551 = 8717690
181 + 8717509 = 8717690
199 + 8717491 = 8717690
337 + 8717353 = 8717690
349 + 8717341 = 8717690

Showing the first eight; more decompositions exist.
