Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711420, here are decompositions:

  • 19 + 8711401 = 8711420
  • 37 + 8711383 = 8711420
  • 43 + 8711377 = 8711420
  • 61 + 8711359 = 8711420
  • 73 + 8711347 = 8711420
  • 241 + 8711179 = 8711420
  • 283 + 8711137 = 8711420
  • 337 + 8711083 = 8711420

Showing the first eight; more decompositions exist.
