Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735724, here are decompositions:

13 + 8735711 = 8735724
43 + 8735681 = 8735724
47 + 8735677 = 8735724
103 + 8735621 = 8735724
167 + 8735557 = 8735724
271 + 8735453 = 8735724
281 + 8735443 = 8735724
307 + 8735417 = 8735724

Showing the first eight; more decompositions exist.
