Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543942, here are decompositions:

  • 29 + 31543913 = 31543942
  • 71 + 31543871 = 31543942
  • 83 + 31543859 = 31543942
  • 113 + 31543829 = 31543942
  • 173 + 31543769 = 31543942
  • 179 + 31543763 = 31543942
  • 191 + 31543751 = 31543942
  • 251 + 31543691 = 31543942

Showing the first eight; more decompositions exist.
