Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720510, here are decompositions:

13 + 8720497 = 8720510
31 + 8720479 = 8720510
79 + 8720431 = 8720510
103 + 8720407 = 8720510
163 + 8720347 = 8720510
193 + 8720317 = 8720510
199 + 8720311 = 8720510
229 + 8720281 = 8720510

Showing the first eight; more decompositions exist.
