Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644972, here are decompositions:

23 + 8644949 = 8644972
53 + 8644919 = 8644972
59 + 8644913 = 8644972
173 + 8644799 = 8644972
191 + 8644781 = 8644972
269 + 8644703 = 8644972
293 + 8644679 = 8644972
311 + 8644661 = 8644972

Showing the first eight; more decompositions exist.
