Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642608, here are decompositions:

  • 17 + 8642591 = 8642608
  • 41 + 8642567 = 8642608
  • 89 + 8642519 = 8642608
  • 101 + 8642507 = 8642608
  • 179 + 8642429 = 8642608
  • 419 + 8642189 = 8642608
  • 449 + 8642159 = 8642608
  • 461 + 8642147 = 8642608

Showing the first eight; more decompositions exist.
