Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668072, here are decompositions:

5 + 8668067 = 8668072
11 + 8668061 = 8668072
29 + 8668043 = 8668072
41 + 8668031 = 8668072
71 + 8668001 = 8668072
173 + 8667899 = 8668072
251 + 8667821 = 8668072
263 + 8667809 = 8668072

Showing the first eight; more decompositions exist.
