Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591982, here are decompositions:

19 + 8591963 = 8591982
41 + 8591941 = 8591982
73 + 8591909 = 8591982
83 + 8591899 = 8591982
151 + 8591831 = 8591982
173 + 8591809 = 8591982
211 + 8591771 = 8591982
271 + 8591711 = 8591982

Showing the first eight; more decompositions exist.
