Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648740, here are decompositions:

3 + 8648737 = 8648740
11 + 8648729 = 8648740
53 + 8648687 = 8648740
197 + 8648543 = 8648740
227 + 8648513 = 8648740
239 + 8648501 = 8648740
281 + 8648459 = 8648740
293 + 8648447 = 8648740

Showing the first eight; more decompositions exist.
