Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720484, here are decompositions:

5 + 8720479 = 8720484
7 + 8720477 = 8720484
13 + 8720471 = 8720484
37 + 8720447 = 8720484
53 + 8720431 = 8720484
67 + 8720417 = 8720484
137 + 8720347 = 8720484
163 + 8720321 = 8720484

Showing the first eight; more decompositions exist.
