Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498110, here are decompositions:

  • 23 + 31498087 = 31498110
  • 41 + 31498069 = 31498110
  • 67 + 31498043 = 31498110
  • 71 + 31498039 = 31498110
  • 101 + 31498009 = 31498110
  • 103 + 31498007 = 31498110
  • 107 + 31498003 = 31498110
  • 113 + 31497997 = 31498110

Showing the first eight; more decompositions exist.
