Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591844, here are decompositions:

13 + 8591831 = 8591844
17 + 8591827 = 8591844
31 + 8591813 = 8591844
71 + 8591773 = 8591844
73 + 8591771 = 8591844
97 + 8591747 = 8591844
127 + 8591717 = 8591844
181 + 8591663 = 8591844

Showing the first eight; more decompositions exist.
