Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668498, here are decompositions:

131 + 8668367 = 8668498
149 + 8668349 = 8668498
197 + 8668301 = 8668498
347 + 8668151 = 8668498
431 + 8668067 = 8668498
467 + 8668031 = 8668498
569 + 8667929 = 8668498
599 + 8667899 = 8668498

Showing the first eight; more decompositions exist.
