Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31950, here are decompositions:

  • 43 + 31907 = 31950
  • 59 + 31891 = 31950
  • 67 + 31883 = 31950
  • 101 + 31849 = 31950
  • 103 + 31847 = 31950
  • 151 + 31799 = 31950
  • 157 + 31793 = 31950
  • 179 + 31771 = 31950

Showing the first eight; more decompositions exist.
