Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536120, here are decompositions:

  • 19 + 31536101 = 31536120
  • 23 + 31536097 = 31536120
  • 59 + 31536061 = 31536120
  • 67 + 31536053 = 31536120
  • 71 + 31536049 = 31536120
  • 101 + 31536019 = 31536120
  • 103 + 31536017 = 31536120
  • 137 + 31535983 = 31536120

Showing the first eight; more decompositions exist.
