Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668492, here are decompositions:

3 + 8668489 = 8668492
71 + 8668421 = 8668492
89 + 8668403 = 8668492
113 + 8668379 = 8668492
191 + 8668301 = 8668492
359 + 8668133 = 8668492
419 + 8668073 = 8668492
431 + 8668061 = 8668492

Showing the first eight; more decompositions exist.
