Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42004, here are decompositions:

  • 5 + 41999 = 42004
  • 23 + 41981 = 42004
  • 47 + 41957 = 42004
  • 101 + 41903 = 42004
  • 107 + 41897 = 42004
  • 191 + 41813 = 42004
  • 227 + 41777 = 42004
  • 233 + 41771 = 42004

Showing the first eight; more decompositions exist.
