Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644906, here are decompositions:

3 + 8644903 = 8644906
107 + 8644799 = 8644906
227 + 8644679 = 8644906
353 + 8644553 = 8644906
449 + 8644457 = 8644906
467 + 8644439 = 8644906
509 + 8644397 = 8644906
653 + 8644253 = 8644906

Showing the first eight; more decompositions exist.
