Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647744, here are decompositions:

5 + 8647739 = 8647744
47 + 8647697 = 8647744
233 + 8647511 = 8647744
353 + 8647391 = 8647744
467 + 8647277 = 8647744
491 + 8647253 = 8647744
563 + 8647181 = 8647744
587 + 8647157 = 8647744

Showing the first eight; more decompositions exist.
