Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64864, here are decompositions:

  • 11 + 64853 = 64864
  • 47 + 64817 = 64864
  • 53 + 64811 = 64864
  • 71 + 64793 = 64864
  • 83 + 64781 = 64864
  • 101 + 64763 = 64864
  • 197 + 64667 = 64864
  • 251 + 64613 = 64864

Showing the first eight; more decompositions exist.
