Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31954, here are decompositions:

  • 47 + 31907 = 31954
  • 71 + 31883 = 31954
  • 107 + 31847 = 31954
  • 137 + 31817 = 31954
  • 227 + 31727 = 31954
  • 233 + 31721 = 31954
  • 311 + 31643 = 31954
  • 347 + 31607 = 31954

Showing the first eight; more decompositions exist.
