Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722558, here are decompositions:

  • 17 + 8722541 = 8722558
  • 41 + 8722517 = 8722558
  • 59 + 8722499 = 8722558
  • 149 + 8722409 = 8722558
  • 167 + 8722391 = 8722558
  • 191 + 8722367 = 8722558
  • 197 + 8722361 = 8722558
  • 227 + 8722331 = 8722558

Showing the first eight; more decompositions exist.
