Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649278, here are decompositions:

37 + 8649241 = 8649278
67 + 8649211 = 8649278
199 + 8649079 = 8649278
229 + 8649049 = 8649278
277 + 8649001 = 8649278
349 + 8648929 = 8649278
397 + 8648881 = 8649278
439 + 8648839 = 8649278

Showing the first eight; more decompositions exist.
