Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644618, here are decompositions:

11 + 8644607 = 8644618
89 + 8644529 = 8644618
107 + 8644511 = 8644618
167 + 8644451 = 8644618
179 + 8644439 = 8644618
317 + 8644301 = 8644618
431 + 8644187 = 8644618
461 + 8644157 = 8644618

Showing the first eight; more decompositions exist.
