Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29880, here are decompositions:

  • 7 + 29873 = 29880
  • 13 + 29867 = 29880
  • 17 + 29863 = 29880
  • 29 + 29851 = 29880
  • 43 + 29837 = 29880
  • 47 + 29833 = 29880
  • 61 + 29819 = 29880
  • 127 + 29753 = 29880

Showing the first eight; more decompositions exist.
