Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669028, here are decompositions:

61 + 8668967 = 8669028
127 + 8668901 = 8669028
131 + 8668897 = 8669028
139 + 8668889 = 8669028
191 + 8668837 = 8669028
197 + 8668831 = 8669028
211 + 8668817 = 8669028
227 + 8668801 = 8669028

Showing the first eight; more decompositions exist.
