Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644472, here are decompositions:

19 + 8644453 = 8644472
211 + 8644261 = 8644472
229 + 8644243 = 8644472
241 + 8644231 = 8644472
349 + 8644123 = 8644472
751 + 8643721 = 8644472
853 + 8643619 = 8644472
883 + 8643589 = 8644472

Showing the first eight; more decompositions exist.
