Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644632, here are decompositions:

23 + 8644609 = 8644632
79 + 8644553 = 8644632
103 + 8644529 = 8644632
131 + 8644501 = 8644632
179 + 8644453 = 8644632
181 + 8644451 = 8644632
193 + 8644439 = 8644632
331 + 8644301 = 8644632

Showing the first eight; more decompositions exist.
