Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648664, here are decompositions:

107 + 8648557 = 8648664
113 + 8648551 = 8648664
127 + 8648537 = 8648664
131 + 8648533 = 8648664
151 + 8648513 = 8648664
163 + 8648501 = 8648664
251 + 8648413 = 8648664
293 + 8648371 = 8648664

Showing the first eight; more decompositions exist.
