Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668540, here are decompositions:

17 + 8668523 = 8668540
137 + 8668403 = 8668540
173 + 8668367 = 8668540
191 + 8668349 = 8668540
239 + 8668301 = 8668540
347 + 8668193 = 8668540
383 + 8668157 = 8668540
389 + 8668151 = 8668540

Showing the first eight; more decompositions exist.
