Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536900, here are decompositions:

  • 29 + 31536871 = 31536900
  • 37 + 31536863 = 31536900
  • 53 + 31536847 = 31536900
  • 71 + 31536829 = 31536900
  • 79 + 31536821 = 31536900
  • 107 + 31536793 = 31536900
  • 127 + 31536773 = 31536900
  • 167 + 31536733 = 31536900

Showing the first eight; more decompositions exist.
