Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715144, here are decompositions:

  • 37 + 8715107 = 8715144
  • 41 + 8715103 = 8715144
  • 103 + 8715041 = 8715144
  • 131 + 8715013 = 8715144
  • 181 + 8714963 = 8715144
  • 197 + 8714947 = 8715144
  • 223 + 8714921 = 8715144
  • 241 + 8714903 = 8715144

Showing the first eight; more decompositions exist.
