Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644888, here are decompositions:

  • 89 + 8644799 = 8644888
  • 107 + 8644781 = 8644888
  • 137 + 8644751 = 8644888
  • 227 + 8644661 = 8644888
  • 281 + 8644607 = 8644888
  • 359 + 8644529 = 8644888
  • 389 + 8644499 = 8644888
  • 431 + 8644457 = 8644888

Showing the first eight; more decompositions exist.
