Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42204, here are decompositions:

  • 7 + 42197 = 42204
  • 11 + 42193 = 42204
  • 17 + 42187 = 42204
  • 23 + 42181 = 42204
  • 47 + 42157 = 42204
  • 73 + 42131 = 42204
  • 103 + 42101 = 42204
  • 131 + 42073 = 42204

Showing the first eight; more decompositions exist.
