Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644948, here are decompositions:

29 + 8644919 = 8644948
149 + 8644799 = 8644948
167 + 8644781 = 8644948
197 + 8644751 = 8644948
269 + 8644679 = 8644948
419 + 8644529 = 8644948
449 + 8644499 = 8644948
491 + 8644457 = 8644948

Showing the first eight; more decompositions exist.
