Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535196, here are decompositions:

  • 13 + 31535183 = 31535196
  • 23 + 31535173 = 31535196
  • 53 + 31535143 = 31535196
  • 73 + 31535123 = 31535196
  • 83 + 31535113 = 31535196
  • 89 + 31535107 = 31535196
  • 113 + 31535083 = 31535196
  • 137 + 31535059 = 31535196

Showing the first eight; more decompositions exist.
