Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720414, here are decompositions:

7 + 8720407 = 8720414
67 + 8720347 = 8720414
97 + 8720317 = 8720414
103 + 8720311 = 8720414
181 + 8720233 = 8720414
223 + 8720191 = 8720414
277 + 8720137 = 8720414
463 + 8719951 = 8720414

Showing the first eight; more decompositions exist.
