Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669138, here are decompositions:

31 + 8669107 = 8669138
67 + 8669071 = 8669138
97 + 8669041 = 8669138
241 + 8668897 = 8669138
307 + 8668831 = 8669138
337 + 8668801 = 8669138
397 + 8668741 = 8669138
619 + 8668519 = 8669138

Showing the first eight; more decompositions exist.
