Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497896, here are decompositions:

  • 13 + 31497883 = 31497896
  • 37 + 31497859 = 31497896
  • 139 + 31497757 = 31497896
  • 223 + 31497673 = 31497896
  • 229 + 31497667 = 31497896
  • 337 + 31497559 = 31497896
  • 349 + 31497547 = 31497896
  • 373 + 31497523 = 31497896

Showing the first eight; more decompositions exist.
