Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645944, here are decompositions:

3 + 8645941 = 8645944
17 + 8645927 = 8645944
257 + 8645687 = 8645944
311 + 8645633 = 8645944
347 + 8645597 = 8645944
401 + 8645543 = 8645944
467 + 8645477 = 8645944
563 + 8645381 = 8645944

Showing the first eight; more decompositions exist.
