Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722132, here are decompositions:

  • 53 + 8722079 = 8722132
  • 113 + 8722019 = 8722132
  • 131 + 8722001 = 8722132
  • 191 + 8721941 = 8722132
  • 281 + 8721851 = 8722132
  • 359 + 8721773 = 8722132
  • 383 + 8721749 = 8722132
  • 431 + 8721701 = 8722132

Showing the first eight; more decompositions exist.
