Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476840, here are decompositions:

  • 11 + 31476829 = 31476840
  • 19 + 31476821 = 31476840
  • 41 + 31476799 = 31476840
  • 97 + 31476743 = 31476840
  • 107 + 31476733 = 31476840
  • 113 + 31476727 = 31476840
  • 137 + 31476703 = 31476840
  • 149 + 31476691 = 31476840

Showing the first eight; more decompositions exist.
