Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731308, here are decompositions:

7 + 8731301 = 8731308
31 + 8731277 = 8731308
59 + 8731249 = 8731308
97 + 8731211 = 8731308
107 + 8731201 = 8731308
167 + 8731141 = 8731308
197 + 8731111 = 8731308
199 + 8731109 = 8731308

Showing the first eight; more decompositions exist.
