Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668972, here are decompositions:

5 + 8668967 = 8668972
71 + 8668901 = 8668972
83 + 8668889 = 8668972
173 + 8668799 = 8668972
233 + 8668739 = 8668972
251 + 8668721 = 8668972
359 + 8668613 = 8668972
401 + 8668571 = 8668972

Showing the first eight; more decompositions exist.
