Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731108, here are decompositions:

5 + 8731103 = 8731108
11 + 8731097 = 8731108
131 + 8730977 = 8731108
179 + 8730929 = 8731108
227 + 8730881 = 8731108
251 + 8730857 = 8731108
257 + 8730851 = 8731108
311 + 8730797 = 8731108

Showing the first eight; more decompositions exist.
