Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668318, here are decompositions:

17 + 8668301 = 8668318
167 + 8668151 = 8668318
251 + 8668067 = 8668318
257 + 8668061 = 8668318
317 + 8668001 = 8668318
389 + 8667929 = 8668318
419 + 8667899 = 8668318
509 + 8667809 = 8668318

Showing the first eight; more decompositions exist.
