Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731460, here are decompositions:

13 + 8731447 = 8731460
43 + 8731417 = 8731460
79 + 8731381 = 8731460
97 + 8731363 = 8731460
139 + 8731321 = 8731460
151 + 8731309 = 8731460
211 + 8731249 = 8731460
229 + 8731231 = 8731460

Showing the first eight; more decompositions exist.
