Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668530, here are decompositions:

7 + 8668523 = 8668530
11 + 8668519 = 8668530
29 + 8668501 = 8668530
41 + 8668489 = 8668530
47 + 8668483 = 8668530
71 + 8668459 = 8668530
107 + 8668423 = 8668530
109 + 8668421 = 8668530

Showing the first eight; more decompositions exist.
