Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610870, here are decompositions:

  • 7 + 8610863 = 8610870
  • 19 + 8610851 = 8610870
  • 41 + 8610829 = 8610870
  • 43 + 8610827 = 8610870
  • 67 + 8610803 = 8610870
  • 131 + 8610739 = 8610870
  • 139 + 8610731 = 8610870
  • 211 + 8610659 = 8610870

Showing the first eight; more decompositions exist.
