Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748686, here are decompositions:

13 + 8748673 = 8748686
43 + 8748643 = 8748686
97 + 8748589 = 8748686
103 + 8748583 = 8748686
223 + 8748463 = 8748686
283 + 8748403 = 8748686
409 + 8748277 = 8748686
487 + 8748199 = 8748686

Showing the first eight; more decompositions exist.
