Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661936, here are decompositions:

  • 37 + 8661899 = 8661936
  • 47 + 8661889 = 8661936
  • 53 + 8661883 = 8661936
  • 97 + 8661839 = 8661936
  • 137 + 8661799 = 8661936
  • 167 + 8661769 = 8661936
  • 193 + 8661743 = 8661936
  • 229 + 8661707 = 8661936

Showing the first eight; more decompositions exist.
