Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731332, here are decompositions:

11 + 8731321 = 8731332
19 + 8731313 = 8731332
23 + 8731309 = 8731332
31 + 8731301 = 8731332
83 + 8731249 = 8731332
101 + 8731231 = 8731332
131 + 8731201 = 8731332
179 + 8731153 = 8731332

Showing the first eight; more decompositions exist.
