Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641912, here are decompositions:

3 + 8641909 = 8641912
29 + 8641883 = 8641912
131 + 8641781 = 8641912
179 + 8641733 = 8641912
239 + 8641673 = 8641912
269 + 8641643 = 8641912
281 + 8641631 = 8641912
443 + 8641469 = 8641912

Showing the first eight; more decompositions exist.
