Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644772, here are decompositions:

43 + 8644729 = 8644772
139 + 8644633 = 8644772
163 + 8644609 = 8644772
271 + 8644501 = 8644772
541 + 8644231 = 8644772
601 + 8644171 = 8644772
691 + 8644081 = 8644772
853 + 8643919 = 8644772

Showing the first eight; more decompositions exist.
