Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668488, here are decompositions:

5 + 8668483 = 8668488
29 + 8668459 = 8668488
67 + 8668421 = 8668488
107 + 8668381 = 8668488
109 + 8668379 = 8668488
131 + 8668357 = 8668488
139 + 8668349 = 8668488
281 + 8668207 = 8668488

Showing the first eight; more decompositions exist.
