Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644668, here are decompositions:

7 + 8644661 = 8644668
17 + 8644651 = 8644668
59 + 8644609 = 8644668
61 + 8644607 = 8644668
139 + 8644529 = 8644668
157 + 8644511 = 8644668
167 + 8644501 = 8644668
191 + 8644477 = 8644668

Showing the first eight; more decompositions exist.
