Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591874, here are decompositions:

43 + 8591831 = 8591874
47 + 8591827 = 8591874
61 + 8591813 = 8591874
101 + 8591773 = 8591874
103 + 8591771 = 8591874
127 + 8591747 = 8591874
157 + 8591717 = 8591874
163 + 8591711 = 8591874

Showing the first eight; more decompositions exist.
