Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30976, here are decompositions:

  • 5 + 30971 = 30976
  • 83 + 30893 = 30976
  • 107 + 30869 = 30976
  • 137 + 30839 = 30976
  • 167 + 30809 = 30976
  • 173 + 30803 = 30976
  • 263 + 30713 = 30976
  • 269 + 30707 = 30976

Showing the first eight; more decompositions exist.
