Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667870, here are decompositions:

  • 7 + 8667863 = 8667870
  • 23 + 8667847 = 8667870
  • 41 + 8667829 = 8667870
  • 61 + 8667809 = 8667870
  • 73 + 8667797 = 8667870
  • 137 + 8667733 = 8667870
  • 149 + 8667721 = 8667870
  • 163 + 8667707 = 8667870

Showing the first eight; more decompositions exist.
