Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598100, here are decompositions:

  • 43 + 31598057 = 31598100
  • 67 + 31598033 = 31598100
  • 71 + 31598029 = 31598100
  • 73 + 31598027 = 31598100
  • 89 + 31598011 = 31598100
  • 103 + 31597997 = 31598100
  • 113 + 31597987 = 31598100
  • 139 + 31597961 = 31598100

Showing the first eight; more decompositions exist.
