Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731908, here are decompositions:

7 + 8731901 = 8731908
41 + 8731867 = 8731908
47 + 8731861 = 8731908
89 + 8731819 = 8731908
131 + 8731777 = 8731908
151 + 8731757 = 8731908
197 + 8731711 = 8731908
271 + 8731637 = 8731908

Showing the first eight; more decompositions exist.
