Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644964, here are decompositions:

7 + 8644957 = 8644964
37 + 8644927 = 8644964
61 + 8644903 = 8644964
103 + 8644861 = 8644964
193 + 8644771 = 8644964
241 + 8644723 = 8644964
313 + 8644651 = 8644964
331 + 8644633 = 8644964

Showing the first eight; more decompositions exist.
