Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648584, here are decompositions:

41 + 8648543 = 8648584
47 + 8648537 = 8648584
53 + 8648531 = 8648584
71 + 8648513 = 8648584
83 + 8648501 = 8648584
137 + 8648447 = 8648584
251 + 8648333 = 8648584
317 + 8648267 = 8648584

Showing the first eight; more decompositions exist.
