Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461976, here are decompositions:

  • 53 + 31461923 = 31461976
  • 83 + 31461893 = 31461976
  • 89 + 31461887 = 31461976
  • 197 + 31461779 = 31461976
  • 233 + 31461743 = 31461976
  • 239 + 31461737 = 31461976
  • 419 + 31461557 = 31461976
  • 443 + 31461533 = 31461976

Showing the first eight; more decompositions exist.
