Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730870, here are decompositions:

  • 7 + 8730863 = 8730870
  • 11 + 8730859 = 8730870
  • 13 + 8730857 = 8730870
  • 19 + 8730851 = 8730870
  • 23 + 8730847 = 8730870
  • 67 + 8730803 = 8730870
  • 73 + 8730797 = 8730870
  • 89 + 8730781 = 8730870

Showing the first eight; more decompositions exist.
