Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461836, here are decompositions:

  • 13 + 31461823 = 31461836
  • 19 + 31461817 = 31461836
  • 73 + 31461763 = 31461836
  • 139 + 31461697 = 31461836
  • 163 + 31461673 = 31461836
  • 283 + 31461553 = 31461836
  • 313 + 31461523 = 31461836
  • 349 + 31461487 = 31461836

Showing the first eight; more decompositions exist.
