Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731310, here are decompositions:

61 + 8731249 = 8731310
79 + 8731231 = 8731310
97 + 8731213 = 8731310
109 + 8731201 = 8731310
157 + 8731153 = 8731310
199 + 8731111 = 8731310
241 + 8731069 = 8731310
271 + 8731039 = 8731310

Showing the first eight; more decompositions exist.
