Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669948, here are decompositions:

19 + 8669929 = 8669948
37 + 8669911 = 8669948
127 + 8669821 = 8669948
181 + 8669767 = 8669948
277 + 8669671 = 8669948
337 + 8669611 = 8669948
421 + 8669527 = 8669948
607 + 8669341 = 8669948

Showing the first eight; more decompositions exist.
