Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81204, here are decompositions:

  • 5 + 81199 = 81204
  • 7 + 81197 = 81204
  • 23 + 81181 = 81204
  • 31 + 81173 = 81204
  • 41 + 81163 = 81204
  • 47 + 81157 = 81204
  • 73 + 81131 = 81204
  • 103 + 81101 = 81204

Showing the first eight; more decompositions exist.
