Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691260, here are decompositions:

13 + 8691247 = 8691260
31 + 8691229 = 8691260
37 + 8691223 = 8691260
73 + 8691187 = 8691260
103 + 8691157 = 8691260
241 + 8691019 = 8691260
307 + 8690953 = 8691260
313 + 8690947 = 8691260

Showing the first eight; more decompositions exist.
