Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731338, here are decompositions:

17 + 8731321 = 8731338
29 + 8731309 = 8731338
37 + 8731301 = 8731338
61 + 8731277 = 8731338
89 + 8731249 = 8731338
107 + 8731231 = 8731338
127 + 8731211 = 8731338
137 + 8731201 = 8731338

Showing the first eight; more decompositions exist.
