Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722432, here are decompositions:

  • 3 + 8722429 = 8722432
  • 23 + 8722409 = 8722432
  • 41 + 8722391 = 8722432
  • 71 + 8722361 = 8722432
  • 101 + 8722331 = 8722432
  • 149 + 8722283 = 8722432
  • 239 + 8722193 = 8722432
  • 263 + 8722169 = 8722432

Showing the first eight; more decompositions exist.
