Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644208, here are decompositions:

  • 37 + 8644171 = 8644208
  • 61 + 8644147 = 8644208
  • 127 + 8644081 = 8644208
  • 151 + 8644057 = 8644208
  • 211 + 8643997 = 8644208
  • 421 + 8643787 = 8644208
  • 487 + 8643721 = 8644208
  • 577 + 8643631 = 8644208

Showing the first eight; more decompositions exist.
