Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731678, here are decompositions:

5 + 8731673 = 8731678
17 + 8731661 = 8731678
41 + 8731637 = 8731678
71 + 8731607 = 8731678
107 + 8731571 = 8731678
149 + 8731529 = 8731678
167 + 8731511 = 8731678
251 + 8731427 = 8731678

Showing the first eight; more decompositions exist.
