Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668814, here are decompositions:

13 + 8668801 = 8668814
31 + 8668783 = 8668814
73 + 8668741 = 8668814
103 + 8668711 = 8668814
127 + 8668687 = 8668814
313 + 8668501 = 8668814
331 + 8668483 = 8668814
433 + 8668381 = 8668814

Showing the first eight; more decompositions exist.
