Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641906, here are decompositions:

23 + 8641883 = 8641906
89 + 8641817 = 8641906
173 + 8641733 = 8641906
197 + 8641709 = 8641906
233 + 8641673 = 8641906
263 + 8641643 = 8641906
293 + 8641613 = 8641906
359 + 8641547 = 8641906

Showing the first eight; more decompositions exist.
