Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644630, here are decompositions:

23 + 8644607 = 8644630
101 + 8644529 = 8644630
131 + 8644499 = 8644630
173 + 8644457 = 8644630
179 + 8644451 = 8644630
191 + 8644439 = 8644630
233 + 8644397 = 8644630
443 + 8644187 = 8644630

Showing the first eight; more decompositions exist.
