Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667390, here are decompositions:

  • 13 + 8667377 = 8667390
  • 19 + 8667371 = 8667390
  • 41 + 8667349 = 8667390
  • 71 + 8667319 = 8667390
  • 89 + 8667301 = 8667390
  • 101 + 8667289 = 8667390
  • 163 + 8667227 = 8667390
  • 211 + 8667179 = 8667390

Showing the first eight; more decompositions exist.
