Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745680, here are decompositions:

3 + 8745677 = 8745680
43 + 8745637 = 8745680
67 + 8745613 = 8745680
109 + 8745571 = 8745680
127 + 8745553 = 8745680
157 + 8745523 = 8745680
313 + 8745367 = 8745680
337 + 8745343 = 8745680

Showing the first eight; more decompositions exist.
