Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641120, here are decompositions:

23 + 8641097 = 8641120
41 + 8641079 = 8641120
113 + 8641007 = 8641120
233 + 8640887 = 8641120
353 + 8640767 = 8641120
359 + 8640761 = 8641120
401 + 8640719 = 8641120
419 + 8640701 = 8641120

Showing the first eight; more decompositions exist.
