Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669144, here are decompositions:

31 + 8669113 = 8669144
37 + 8669107 = 8669144
61 + 8669083 = 8669144
73 + 8669071 = 8669144
103 + 8669041 = 8669144
151 + 8668993 = 8669144
193 + 8668951 = 8669144
271 + 8668873 = 8669144

Showing the first eight; more decompositions exist.
