Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707120, here are decompositions:

  • 17 + 8707103 = 8707120
  • 29 + 8707091 = 8707120
  • 83 + 8707037 = 8707120
  • 89 + 8707031 = 8707120
  • 113 + 8707007 = 8707120
  • 137 + 8706983 = 8707120
  • 167 + 8706953 = 8707120
  • 173 + 8706947 = 8707120

Showing the first eight; more decompositions exist.
