Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29906, here are decompositions:

  • 43 + 29863 = 29906
  • 73 + 29833 = 29906
  • 103 + 29803 = 29906
  • 223 + 29683 = 29906
  • 277 + 29629 = 29906
  • 307 + 29599 = 29906
  • 337 + 29569 = 29906
  • 379 + 29527 = 29906

Showing the first eight; more decompositions exist.
