Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25784, here are decompositions:

  • 13 + 25771 = 25784
  • 37 + 25747 = 25784
  • 43 + 25741 = 25784
  • 67 + 25717 = 25784
  • 127 + 25657 = 25784
  • 151 + 25633 = 25784
  • 163 + 25621 = 25784
  • 181 + 25603 = 25784

Showing the first eight; more decompositions exist.
