Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658144, here are decompositions:

7 + 8658137 = 8658144
37 + 8658107 = 8658144
41 + 8658103 = 8658144
43 + 8658101 = 8658144
101 + 8658043 = 8658144
127 + 8658017 = 8658144
211 + 8657933 = 8658144
241 + 8657903 = 8658144

Showing the first eight; more decompositions exist.
