Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25880, here are decompositions:

  • 7 + 25873 = 25880
  • 13 + 25867 = 25880
  • 31 + 25849 = 25880
  • 61 + 25819 = 25880
  • 79 + 25801 = 25880
  • 109 + 25771 = 25880
  • 139 + 25741 = 25880
  • 163 + 25717 = 25880

Showing the first eight; more decompositions exist.
