Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722402, here are decompositions:

  • 11 + 8722391 = 8722402
  • 41 + 8722361 = 8722402
  • 71 + 8722331 = 8722402
  • 179 + 8722223 = 8722402
  • 191 + 8722211 = 8722402
  • 233 + 8722169 = 8722402
  • 383 + 8722019 = 8722402
  • 401 + 8722001 = 8722402

Showing the first eight; more decompositions exist.
