Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641126, here are decompositions:

29 + 8641097 = 8641126
47 + 8641079 = 8641126
149 + 8640977 = 8641126
239 + 8640887 = 8641126
359 + 8640767 = 8641126
419 + 8640707 = 8641126
443 + 8640683 = 8641126
719 + 8640407 = 8641126

Showing the first eight; more decompositions exist.
