Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720346, here are decompositions:

7 + 8720339 = 8720346
29 + 8720317 = 8720346
113 + 8720233 = 8720346
157 + 8720189 = 8720346
227 + 8720119 = 8720346
233 + 8720113 = 8720346
347 + 8719999 = 8720346
359 + 8719987 = 8720346

Showing the first eight; more decompositions exist.
