Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668808, here are decompositions:

7 + 8668801 = 8668808
67 + 8668741 = 8668808
97 + 8668711 = 8668808
199 + 8668609 = 8668808
307 + 8668501 = 8668808
349 + 8668459 = 8668808
439 + 8668369 = 8668808
541 + 8668267 = 8668808

Showing the first eight; more decompositions exist.
