Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595888, here are decompositions:

  • 7 + 31595881 = 31595888
  • 19 + 31595869 = 31595888
  • 157 + 31595731 = 31595888
  • 277 + 31595611 = 31595888
  • 307 + 31595581 = 31595888
  • 421 + 31595467 = 31595888
  • 787 + 31595101 = 31595888
  • 829 + 31595059 = 31595888

Showing the first eight; more decompositions exist.
