Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31648, here are decompositions:

  • 5 + 31643 = 31648
  • 41 + 31607 = 31648
  • 47 + 31601 = 31648
  • 101 + 31547 = 31648
  • 107 + 31541 = 31648
  • 131 + 31517 = 31648
  • 137 + 31511 = 31648
  • 167 + 31481 = 31648

Showing the first eight; more decompositions exist.
