Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649214, here are decompositions:

3 + 8649211 = 8649214
17 + 8649197 = 8649214
23 + 8649191 = 8649214
191 + 8649023 = 8649214
293 + 8648921 = 8649214
347 + 8648867 = 8649214
383 + 8648831 = 8649214
401 + 8648813 = 8649214

Showing the first eight; more decompositions exist.
