Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720376, here are decompositions:

29 + 8720347 = 8720376
37 + 8720339 = 8720376
59 + 8720317 = 8720376
149 + 8720227 = 8720376
199 + 8720177 = 8720376
239 + 8720137 = 8720376
257 + 8720119 = 8720376
263 + 8720113 = 8720376

Showing the first eight; more decompositions exist.
