Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690864, here are decompositions:

  • 37 + 8690827 = 8690864
  • 43 + 8690821 = 8690864
  • 67 + 8690797 = 8690864
  • 97 + 8690767 = 8690864
  • 151 + 8690713 = 8690864
  • 181 + 8690683 = 8690864
  • 271 + 8690593 = 8690864
  • 307 + 8690557 = 8690864

Showing the first eight; more decompositions exist.
