Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722966, here are decompositions:

  • 17 + 8722949 = 8722966
  • 53 + 8722913 = 8722966
  • 89 + 8722877 = 8722966
  • 107 + 8722859 = 8722966
  • 137 + 8722829 = 8722966
  • 167 + 8722799 = 8722966
  • 227 + 8722739 = 8722966
  • 293 + 8722673 = 8722966

Showing the first eight; more decompositions exist.
