Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658900, here are decompositions:

  • 7 + 8658893 = 8658900
  • 13 + 8658887 = 8658900
  • 23 + 8658877 = 8658900
  • 31 + 8658869 = 8658900
  • 53 + 8658847 = 8658900
  • 71 + 8658829 = 8658900
  • 127 + 8658773 = 8658900
  • 191 + 8658709 = 8658900

Showing the first eight; more decompositions exist.
