Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747226, here are decompositions:

13 + 8747213 = 8747226
67 + 8747159 = 8747226
107 + 8747119 = 8747226
227 + 8746999 = 8747226
263 + 8746963 = 8747226
269 + 8746957 = 8747226
277 + 8746949 = 8747226
307 + 8746919 = 8747226

Showing the first eight; more decompositions exist.
