Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39930, here are decompositions:

  • 29 + 39901 = 39930
  • 43 + 39887 = 39930
  • 47 + 39883 = 39930
  • 53 + 39877 = 39930
  • 61 + 39869 = 39930
  • 67 + 39863 = 39930
  • 73 + 39857 = 39930
  • 83 + 39847 = 39930

Showing the first eight; more decompositions exist.
