Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751290, here are decompositions:

  • 109 + 8751181 = 8751290
  • 139 + 8751151 = 8751290
  • 151 + 8751139 = 8751290
  • 193 + 8751097 = 8751290
  • 199 + 8751091 = 8751290
  • 211 + 8751079 = 8751290
  • 277 + 8751013 = 8751290
  • 283 + 8751007 = 8751290

Showing the first eight; more decompositions exist.
