Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720334, here are decompositions:

13 + 8720321 = 8720334
17 + 8720317 = 8720334
23 + 8720311 = 8720334
53 + 8720281 = 8720334
101 + 8720233 = 8720334
107 + 8720227 = 8720334
157 + 8720177 = 8720334
163 + 8720171 = 8720334

Showing the first eight; more decompositions exist.
