Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519864, here are decompositions:

  • 47 + 519817 = 519864
  • 61 + 519803 = 519864
  • 67 + 519797 = 519864
  • 71 + 519793 = 519864
  • 127 + 519737 = 519864
  • 131 + 519733 = 519864
  • 151 + 519713 = 519864
  • 173 + 519691 = 519864

Showing the first eight; more decompositions exist.
