Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644982, here are decompositions:

19 + 8644963 = 8644982
79 + 8644903 = 8644982
109 + 8644873 = 8644982
139 + 8644843 = 8644982
211 + 8644771 = 8644982
331 + 8644651 = 8644982
349 + 8644633 = 8644982
373 + 8644609 = 8644982

Showing the first eight; more decompositions exist.
