Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720454, here are decompositions:

7 + 8720447 = 8720454
23 + 8720431 = 8720454
37 + 8720417 = 8720454
47 + 8720407 = 8720454
107 + 8720347 = 8720454
137 + 8720317 = 8720454
173 + 8720281 = 8720454
227 + 8720227 = 8720454

Showing the first eight; more decompositions exist.
