Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720498, here are decompositions:

19 + 8720479 = 8720498
67 + 8720431 = 8720498
109 + 8720389 = 8720498
151 + 8720347 = 8720498
181 + 8720317 = 8720498
271 + 8720227 = 8720498
307 + 8720191 = 8720498
337 + 8720161 = 8720498

Showing the first eight; more decompositions exist.
