Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735720, here are decompositions:

43 + 8735677 = 8735720
139 + 8735581 = 8735720
157 + 8735563 = 8735720
163 + 8735557 = 8735720
211 + 8735509 = 8735720
241 + 8735479 = 8735720
271 + 8735449 = 8735720
277 + 8735443 = 8735720

Showing the first eight; more decompositions exist.
