Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720558, here are decompositions:

61 + 8720497 = 8720558
79 + 8720479 = 8720558
127 + 8720431 = 8720558
151 + 8720407 = 8720558
211 + 8720347 = 8720558
241 + 8720317 = 8720558
277 + 8720281 = 8720558
331 + 8720227 = 8720558

Showing the first eight; more decompositions exist.
