Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644860, here are decompositions:

17 + 8644843 = 8644860
61 + 8644799 = 8644860
79 + 8644781 = 8644860
89 + 8644771 = 8644860
109 + 8644751 = 8644860
131 + 8644729 = 8644860
137 + 8644723 = 8644860
157 + 8644703 = 8644860

Showing the first eight; more decompositions exist.
