Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722008, here are decompositions:

  • 7 + 8722001 = 8722008
  • 11 + 8721997 = 8722008
  • 19 + 8721989 = 8722008
  • 67 + 8721941 = 8722008
  • 79 + 8721929 = 8722008
  • 101 + 8721907 = 8722008
  • 131 + 8721877 = 8722008
  • 157 + 8721851 = 8722008

Showing the first eight; more decompositions exist.
