Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648660, here are decompositions:

103 + 8648557 = 8648660
109 + 8648551 = 8648660
127 + 8648533 = 8648660
271 + 8648389 = 8648660
313 + 8648347 = 8648660
337 + 8648323 = 8648660
409 + 8648251 = 8648660
421 + 8648239 = 8648660

Showing the first eight; more decompositions exist.
