Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664072, here are decompositions:

19 + 8664053 = 8664072
29 + 8664043 = 8664072
103 + 8663969 = 8664072
113 + 8663959 = 8664072
149 + 8663923 = 8664072
173 + 8663899 = 8664072
211 + 8663861 = 8664072
251 + 8663821 = 8664072

Showing the first eight; more decompositions exist.
