Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644746, here are decompositions:

17 + 8644729 = 8644746
23 + 8644723 = 8644746
43 + 8644703 = 8644746
67 + 8644679 = 8644746
113 + 8644633 = 8644746
137 + 8644609 = 8644746
139 + 8644607 = 8644746
193 + 8644553 = 8644746

Showing the first eight; more decompositions exist.
