Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27976, here are decompositions:

  • 23 + 27953 = 27976
  • 29 + 27947 = 27976
  • 59 + 27917 = 27976
  • 83 + 27893 = 27976
  • 149 + 27827 = 27976
  • 167 + 27809 = 27976
  • 173 + 27803 = 27976
  • 197 + 27779 = 27976

Showing the first eight; more decompositions exist.
