Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560670, here are decompositions:

  • 23 + 31560647 = 31560670
  • 41 + 31560629 = 31560670
  • 83 + 31560587 = 31560670
  • 101 + 31560569 = 31560670
  • 137 + 31560533 = 31560670
  • 233 + 31560437 = 31560670
  • 263 + 31560407 = 31560670
  • 269 + 31560401 = 31560670

Showing the first eight; more decompositions exist.
