Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745266, here are decompositions:

43 + 8745223 = 8745266
67 + 8745199 = 8745266
97 + 8745169 = 8745266
199 + 8745067 = 8745266
337 + 8744929 = 8745266
349 + 8744917 = 8745266
379 + 8744887 = 8745266
433 + 8744833 = 8745266

Showing the first eight; more decompositions exist.
