Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644832, here are decompositions:

61 + 8644771 = 8644832
103 + 8644729 = 8644832
109 + 8644723 = 8644832
181 + 8644651 = 8644832
199 + 8644633 = 8644832
223 + 8644609 = 8644832
331 + 8644501 = 8644832
379 + 8644453 = 8644832

Showing the first eight; more decompositions exist.
