Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8562, here are decompositions:

  • 19 + 8543 = 8562
  • 23 + 8539 = 8562
  • 41 + 8521 = 8562
  • 61 + 8501 = 8562
  • 101 + 8461 = 8562
  • 131 + 8431 = 8562
  • 139 + 8423 = 8562
  • 173 + 8389 = 8562

Showing the first eight; more decompositions exist.
