Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700900, here are decompositions:

  • 7 + 8700893 = 8700900
  • 29 + 8700871 = 8700900
  • 31 + 8700869 = 8700900
  • 67 + 8700833 = 8700900
  • 73 + 8700827 = 8700900
  • 83 + 8700817 = 8700900
  • 101 + 8700799 = 8700900
  • 107 + 8700793 = 8700900

Showing the first eight; more decompositions exist.
