Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591904, here are decompositions:

5 + 8591899 = 8591904
17 + 8591887 = 8591904
73 + 8591831 = 8591904
131 + 8591773 = 8591904
157 + 8591747 = 8591904
193 + 8591711 = 8591904
241 + 8591663 = 8591904
271 + 8591633 = 8591904

Showing the first eight; more decompositions exist.
