Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641210, here are decompositions:

23 + 8641187 = 8641210
113 + 8641097 = 8641210
131 + 8641079 = 8641210
233 + 8640977 = 8641210
443 + 8640767 = 8641210
449 + 8640761 = 8641210
491 + 8640719 = 8641210
503 + 8640707 = 8641210

Showing the first eight; more decompositions exist.
