Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721060, here are decompositions:

  • 11 + 8721049 = 8721060
  • 17 + 8721043 = 8721060
  • 31 + 8721029 = 8721060
  • 83 + 8720977 = 8721060
  • 107 + 8720953 = 8721060
  • 113 + 8720947 = 8721060
  • 149 + 8720911 = 8721060
  • 223 + 8720837 = 8721060

Showing the first eight; more decompositions exist.
